Modern vehicles have much safer crash characteristics than older cars. The average vehicle on the road in the US is 11 years old. Do you know how much crash characteristics of cars have improved in the last decade? The comparison needs to stay in the modern, $65k+ vehicle realm for it to be apples-to-apples. Otherwise, you're comparing a bunch of decade old rust buckets with heat-cycled rubber, no blind spot monitoring, and Takata airbags to modern vehicles and claiming victory. Come on.

The BMW F10 535i had ZERO FATALITIES over its entire life in the US. Zero. It had no "self-driving" capabilities. Just lane-departure warning, BLIS, and ACC.

Yes, all evidence I've seen indicates that cars partially driven by computers (adaptive cruise control, lane-departure warning, blind spot information, etc.) are safer than cars entirely driven by human beings. The BMW you mention is safer precisely because it is partially driven by machines. The more we automate driving, as machines get better and better at it, the safer we will all be on the road.

Emphasis on PARTIALLY. Anyone who has read recent takeover scenario studies is rightfully horrified at the notion of a completely “hands off” driving experience, where the driver is expected to remain alert and vigilant but they’re not inputting any steering, throttle, or braking. Unsurprisingly, it takes people about 2 seconds to re-engage as active drivers. 2 seconds is way too long, which is why it may be safer to NOT use a system that does steering input in addition to throttle and brake. You need to keep the drivers actively engaged. And no, “touch the steering wheel every 30 seconds” is not active engagement. And if a car has “self driving” but also active driver monitoring, what’s the point? The driver doesn’t get to relax at all. The stress of driving doesn’t come from the input unless you’re racing. The stress of driving comes from having to stay alert. If I have to stay alert, I’d rather just drive myself instead of trusting an experimental system that drives like an indecisive, half-blind grandmother.

The BMW was safe PRIMARILY because it’s a well-designed, modern car, driven by an older and wealthy (safe) demographic. The assistance systems are probably secondary. They weren’t even standard on all vehicles and they were very primitive in that first generation.

If you actually read the Forbes article above, the back of the napkin math actually DOESN’T indicate that Teslas in autopilot are safer than normal driving. That’s the entire contention. I do not think these full-takeover systems are safer at the present time than active human drivers in comparable vehicles with safety assist systems. Tesla is very clearly fudging the numbers to make it appear as if autopilot is safer, but the claim doesn’t stand up to some really basic analysis.
