I can't think of a single website. If someone were looking to create a new automotive website that would be the perfect one to create, a website that allows you to pick options that are on a car.
I had a friend, Robert, visit yesterday. Robert is from Wisconsin and he has cerebral palsy. He is also under 5 feet. He was lamenting about the car issues he has. I wish I could go to a website and click a button that would show me all the cars that had:
pedals that moved back and forth (remember he's short and doesn't want to sit to close to the windshield)
land departure warning (he almost fell asleep once, so he's always concerned about that)
blind spot detection (his neck doesn't turn well, so having the blind spot detection in the side mirrors would be great)
But, alas, no such website.
