A friend of mine just leased the latest Volve SUV (XC90?). We went to lunch in his car. The car is supposed to be able to stay in the current lane and keep a distance from the car before us. On a 40mph road we tested it, and it was able to stay in the lane but the steering wheel adjustments were always lagging what a human would do so you have to have a lot of faith in the car and not override the system. When we came up on a red light with cars stopped there, it didn’t show any sign of wanting to stop so my friend driver had to brake to ease the tension in the cabin.
The new Odyssey has a lot of new safety features but I haven’t gone through them yet. I can provide an update here once/if I come back safely from the testing.
