I still don't understand the hype for them.
The last four vehicles I owned - Escort zx-2 that one had a check engine light come on from a faulty sensor in the first ten thousand miles. Nissan pickup - that one after two years started stalling and stopping on damp days because of a fuel sensor, my mercury sable had a sensor break in the first 5000 miles - when the check engine light popped on , I pulled into the dealership at closing time and forced them to fix it. I have a jeep wrangler now, and whenever the outside temp goes over 89 degrees f and I turn the air conditioning on, the car shudders and jerkes then the check engine light pops on with a low speed idle fault in the OBD (finally bought an obd kit to clear faults to pass inspection).
The point is, I've owned 4 brand new cars, and each car had faults.
How can anyone expect that the car driving itself won't fault and cause cataclysmic accidents? maybe 100,000 cars will be perfect. Maybe a 1,000,000 cars will be perfect. But based on my experience - I'll be freaking terrified if everyone else has self driving cars.
