Emphatically confirmed. We just tried to get from Elektro to Pogorevka with two sedans and we've had everything from loss of control through getting stuck and/or teleporting to not being able to turn the engine off or get out of the car.
The problem got even worse when we passed another car on the way.
Cars control fine when they're far enough away from each other, but as soon as they get in vicinity of another (driveable) vehicle, they start behaving very, very erratically.
