Well that's the thing with cars. Anything the legitimate owner can do because they have physical access, a thief can also do... and even if you force manufacturers to provide a "rooting mode" aka you enter some PIN that you get at purchase into the car's infotainment and it will relax restrictions on the CAN bus, now you open up the gates for thieves as well.

And on top of that come the actual reasons for the security theatre: people modifying their ECUs to tune up their engines for higher power or speed limiters in trucks than is stated in the vehicle papers (at least in Europe, if you tune your vehicle and don't have the papers updated you're in legit felony territory), doing shit mods like "rolling coal" or otherwise tampering with emission controls (say to avoid having to refill adblue)... governments really REALLY do not like this and so regulations get tightened ever closer.
