I can't say that I would ever want one, but I suppose that there will be legislation that makes purchasing one compulsory.
I look at my 2011 4Runner. The map DVD is out of date, but Toyota does not have an update because the vehicle is too old (really -- for a 2011?!).
As well, there are many off camber situations on the road I drive where the stability control (yea, another mandatory government bit of tech) has forced me to go straight though I was in a turn on dry pavement. One time there was a vehicle directly in front of me and I'm still surprised we did not impact.
The sad part is even when I disable stability control, at 15 MPH is automatically is enabled.
Mind you that I've been driving over 30 years and have (knock on wood) never had an accident that I have caused (when I was 16 I was rear ended by a guy driving a '76 Chrysler Cordoba at about 50MPH when he hit me -- I was standing still making a left turn, waiting for traffic to clear).
Hopefully I'll be able to pay for the vehicle and simply remove the crap.
