Yes. And there's a reason why they don't work properly. And they still won't work properly 4 months after the game was released.
CDPR tried to implement car chases and failed. Some gigs that involve car chases were cut off (one can "enjoy" them with the use of saved games that can be found on Nexus). One can also initiate some car chases in Badlands (Militech) and in NC (NCPD). They, obviously, do not work as intended -- the driving AI is not up to the task (it has some serious problems with following the player and/or the road).
I think that we will never see any car chases in the game. CDPR could not make them work properly in this engine (as an important and bug-free part of all these complicated game systems that, as we know, still have their own unresolved problems that needs to be patched). The remnants of this unfinished feature show that AI has some serious problems with maneuvering through obstacles, following the player, simulating collisions and registering the environment (and other NPCs). Mind that there's no sophisticated "driving AI" in the game: vehicles follow prescripted path and are not able to change it during their "lifespan".
IMHO implementing car chases would require a complete redesign of AI (and e.g. collision) systems in the game and, hence, many weeks of testing. It is not going to happen any time soon. And I dare to say: it's not going to happen at all.
I hope I am wrong...
It's been about 3 and 1/3 months (3 months and 11 days, exactly), and the way some gamers are rounding this up to 4 is actually kinda funny to me. I've seen some people call it 5 months, even, which is some interesting gamer math.
When you consider that a month of development time was lost due to a hack that some people cheered about on reddit and Twitter, I have to be real - I'm not that sympathetic towards the "its been X months" stance. I would even go so far as to say that progress has been coming along at a decent pace when you consider how much work has to be put into making the game more stable on consoles before serious gameplay tweaks can even be considered.
As to the meat of the issue regarding car AI, the general consensus is that the game was rushed, and this idea is supported by the reporting Jason Schreier did on the issue. This leaves a legitimate question as to whether the devs can't
get car chases to work properly, or if they simply didn't have time to
given release deadlines.
And let's give the developers some credit here - there are aspects of this game that show passion and a finely crafted attention to detail (especially in regards to the character development of the game's supporting characters), so I think that the developers are capable of putting the needed effort into fixing the system and will at least attempt to. Also consider that the studio will want to recover as much goodwill from gamers as they're able to for future projects, which means addressing prominent criticisms like the state of police A.I.
Finally, if none of my above ramblings were convincing, consider the broader state of car AI. Do you think that the devs are incapable of creating a car pathing system that can navigate around objects in the road, for example? To me, this very much feels like an aspect of the game that is simply unfinished rather than something that was scrapped due to engine limitations or insufficient ability on the part of the dev team.
