Since you don't mention anything particularly dystopian, I shall not go there, not the places that leads.
As to "routine" considerations for what you envision, if you've ever played GTA or seen YouTube clips of it, the word "jacking" is probably in your vocabulary. All those vehicles mentioned can be jacked, if one wants to go past the "just use them creatively" approach. Jack a bus and it goes where you want, when you want. Barring obstruction by law enforcement. Hence the likelihood of having to switch along the way. Even trains and subways can be taken, especially with help on the inside clearing routes for you. But parked subway trains can be left and another entered, normally, and abnormally, through simple leaving through rear doors directly to another or through windows that are side-by-side. Even moving, especially if moving the same direction and near the same speeds.
A train might be left for its roof, then to exit it via pre-positioned or confederate provided ways up to overpassing roadways/people movers/etc.
As mentioned by
Thorne, loot can be handed off to confederates. One of our stores got robbed by several young men. They handed the money off to a car of confederates and the police had nothing when they stopped them. Fools robbed us on a Sunday, not a Saturday. "Fools" because the ninth individual was an employee of ours who knew there was 10 times the money on a Saturday night. Very clever of them otherwise. Not completely otherwise as they did exactly the same thing again the next week and got caught during the handoff. So things might not work with the smoothness of MI, but...
As to actual loot, there could always be inside men at the bank or what-have-you. I remember a John Travolta/Olivia Newton-John movie in which he got nothing, she, the teller, got thousands, and was wrong that he'd figure that out. But with an insider, perhaps one could score quite a few bucks, more than the usual a simple robber gets.
It could even be a beard for an electronic robbery. At some point, before too much mayhem or harm to bystanders occurs for the po-po to drop the chase, the fact that they actually took nothing, or that they dropped it ("lost" it)(the physical loot), might lead to the cops downgrading the chase. If they had some cleverness planned for not long afterward, the confusion as cops are called off and the cleverness might get them away.
They could also be throwaways. A mastermind plans for them to be caught and they acquiesce. It would have to be for a LOT of money, not really what robbers usually get because they'd be going to jail, but even crooks have relatives, children, parents, folks who get expensive to cure cancers or need some other operation. National Health fixed the burns medically, but the hideous appearance costs cash to fix. Scum trying to score to open a business or buy their first 10 kilos of cocaine. That kind of thing. The loot is passed to confederates, then the chase continues for some length of time, the coppers gradually win, and a DB Cooper-like search commences for the lost loot. But it ain't lost. Those throwaways get their share so others will do it again for the mastermind, or at least, their nominees get their shares that is.
To enter a bit of shadow, as opposed to going dark, like I do below, anyone could turn out to be in on it. A politician just happens to drive by at the right time and his car is jacked. Po-po's in on it, some of them, especially folks who can fuzz (pun intended) the electronic stuff. The perps flee through a gang area and the gang rises up to say "Oh no po-po, you ain't passing through our territory." They only need to stick to it long enough to let the robbers get their break from immediate pursuit, then bow to overwhelming police presence. Of course, a plot direction change could occur as they take money for the work before the robbery but disappear the robbers as they come through, maybe even have similar people to continue the run from the cops, and they take the loot. They might have time to disappear it too if the runners give the cops a good run and they have the resources.
Back to the nicer thoughts, they could create mayhem several places along the way, mayhem that breaches usually inviolate facilities. That could be the point. They'll get caught, or won't, but the real robbery might commence in one of the mayhem sites. Or several of them. Perhaps some electronic insertion, done by someone who now has access with the blown out hole in the wall and evacuated building. Or an insider there who is waiting to use the "distraction" to overcome physical limits preventing his taking over a system. One perhaps that has millions available for looting, or perhaps a longer game, using the insertion to crack something much larger.
Smash the window of a storefront dentist office and you might steal 2-3-4,000 records before the cops get there, and mine them slowly by hand for useful data to sell or use. Break in electronically and you steal 10,000 records in a minute or two, then mine them swiftly for information. Credit card info for instance, that won't be more and more useless as people get new cards, since you use in in hours, not weeks. (Oh, all the posing aside, everyone, EVERYONE, holds credit card info even though they're not allowed to, just because customers want that in many cases, and because of bogus disputes and other reasons. I know VISA will be just shocked, shocked that there's record holding going on. Ah, Capablanca, the gift that keeps on giving.)
Hate to go DARK, as you don't seem to be aimed there so won't likely have use for it, but when you take away the easy-to-hope-on getaway methods, there are others. The loot is gathered. The bad guys (and they are BAD) are ready to get away from there. The cops are ringed about. Hostage time. Well, no. One goes out. Slides a phone along the ground. A cop views the video on it. It's a truck's trailer, somewhere, maybe this city, maybe a thousand miles away. Coupla guys in it with submachine guns, clearly another who is filming, and there's a family on its knees, momma, 2-3 kids, that kind of thing. Maybe lying facedown, naked to add shock and wretchedness, and a text overlay that says let the boyos go and don't follow, don't track. Or these people all die. Then it fades off and one of the submachine gun boys puts his gun down and lights up a homemade flamethrower.
Up to the cops.
Frankly, I'm surprised no one's done it yet in our time. Talk about a Hobson's choice.
Keeping it light, PLANNING is really the key. And not crackhead planning, not "I need $4,000 by Thursday" planning, but real, master thief planning. In the '30's it was thought the mob and others had a stable of such who'd make plans for any given heist, bank, jeweler's, home invasion, payrolls, whatever. They were not participants, just made plans. And that there were freelancers who did the same and found men (and women) to do the work, taking a split, or a buy-out and walking away, leaving the thieves to it. I wrote some stories and got mostly done on a novel on that idea, set near the Mexican border (Texas), but it seems I'm not a... compelling... writer. (Well, to be honest, not a good one, I guess.) It morphed into the movie standard of con gangs running deep games, even nice guy ones like in Leverage but I bet people nowadays would buy back into the masterminds writing up robberies and other heists though. Not necessarily the organized crime aspect, but perhaps high-ranking cops and politicians, being run perhaps by rich men.
So maybe think of what there is in your world to give that kind of a twist to their getaway.
There's always the not escaping into a crowd, but when the crowd is tasked by the cops, it goes the "No, I am Spartacus" route. But that requires a slightly shadowed nuance to things as well. There'd have to be a lot of class hate and anger present in what sounds like an otherwise happy world.
