Let us be clear: Vehicles with emergency steering takeover systems do not suddenly become autonomous to bail out the driver in an emergency. What usually happens is that they provide more steering assistance when the driver has to take evasive action. The good thing is, though, that these cars have complementary systems like blind-spot monitoring to stop matters from becoming worse. If a driver is concentrating on an impending disaster ahead, then there often isn’t time to check the mirrors. But the car can.
These features are more often found in luxury vehicles, since that’s where the technological “arms race” happens first. Factor in all the other good stuff that comes with premium cars and it could be money well spent.
