Levels of driving automation is an ill-defined concept. For example, L4 is defined as "mind-off". According to Wikipedia, "the driver may safely go to sleep or leave the driver's seat. Self driving is supported only in limited areas (geofenced) or under special circumstances, like traffic jams. Outside of these areas or circumstances, the vehicle must be able to safely abort the trip, i.e. park the car, if the driver…
> the driver may safely go to sleep or leave the driver's seat That's going to be hard to do while you are wearing a seatbelt and I don't see seatbelt laws rescinded just because a vehicle is self driving until car accidents are exceedingly rare.

That's because the current seats and belts are not designed for comfortable sleeping. This can change if the vehicle has L4 autonomy - the interior can be redesigned to from the ground-up to accommodate sleeping. Airplanes seats have set the precedence of having seat-belts whilst allowing for sleep.

One question I can't seem to find a good answer for is this: Why doesn't the self-driving tech hand off control to a remote driver if the internet connection is good enough and there is enough warning? Even with a couple seconds notice a primed human could take the wheel and do the right thing when the sensors aren't making sense.
There's no good reason; it's likely what they'll do.

While I agree that it's impossible to make predictions, your example is a massive edge case.
I don't think it's an edge case: If an operator redesigns the interior of their fleet with large, comfortable reclining seats, long distance travel by road will become much more competitive with business-/first-class air travel. Boarding at my house and being dropped off at my destination and sleeping all the way (or working if you're a telecommuter, or watching movies) is quite appealing to me - the lack of TSA and/…

#286I own the same model of vehicle as Waymo is using (2017 Pacifica PHEV). It's cool to see how little they've had to visibly modify the car (apart from the sensors)—the interior looks 100% stock, other than the row of buttons on the ceiling. Given the level-1 autonomous features in the vehicle (self-parking, etc.), all of the integrations are probably done over CAN-bus, with no additional hardware required (again, apar…
I think there's more than that. The safety report they released recently indicates the vehicles also have redundant power systems, redundant braking systems, redundant steering systems, etc. I doubt that the stock configurations require as much redundancy.

Airplane seatbelts are only mandatory during take-off and landing as well as turbulence. It will be a very long time before any kind of driving is as safe as commercial air travel.
While not legally mandated, most airlines encourage people to keep their seat-belts on during cruise - this is good advice that I take to heart because turbulence is unpredictable; sudden loss of elevation are known to happen.

#288Throws money at screen Having said that I do love seeing these wide, straight American roads and wonder how well this will do on the tiny (often single track) winding country roads around here.

#289If Waymo's tech is years ahead of the competition (say 18-24 months ahead minimum) then I think a lot of the self-driving companies and car manufacturers in the US will be having cold sweats. This may not be a winner-take-all market (I don't know honestly...) but I see this lead up enabling Waymo to capture significant market share in the US in regions where laws towards autonomous vehicles are friendly. One way the…
Waymo does seem to be ahead technically. They've been working on the hard cases for years, while the other guys are still struggling. They are trying hard to get good situational awareness. One of the few neutral measures we have are CA DMV's disconnect and accident reports, and in those, Waymo has been consistently ahead. Waymo is hooked up with FCA (Fiat-Chrysler Automobiles), of all things. Uber is "fake it 'til y…

I've been on long distance buses with large, comfortable reclining seats and convenient pickup/dropoff points for 8 hour plus journeys more than most sane people I assure you it's not the human driver which means that most people strongly prefer other methods of transport.
For example, right now the idea of a folding bed in a car isn't something you'll ever see as an option, since it would only really appeal to people trying to live in their cars, which probably don't overlap much with the "people who buy fancy cars with fancy extras" market segment. However, in a future where a car can auto-drive you on a long-distance trip, why not offer an actual bed mode in the car as a purchasable option?
