Yep, I don’t think adding up/down is going to make things much better for people who struggle with the current forward/backward left/right combo. Add in the prevalent tendency to neglect preventative maintenance and you’re in for a total shitshow.

#2 arguement: shitty drivers, now in 3d.

You don't get to have a blowout while cruising through the air

I’m still trying to figure out how driverless cars will handle this kind of neglect.

I mean, t ires and brakes are still going to be pretty important... With all the sensors and autonomous car needs already, wi ll they need even more sensors to ensure that the tires and brakes are healthy enough to handle the rigors of driving ? And if such a problem is detected, will the car be automatically “bricked”, or go into limp mode until it’s serviced ?

Or maybe it won’t be sensors. M aybe these HAVs will need inspections every couple of months, and someone will have to look them over and certif y th at it should be good for the next several weeks.

Yeah, that would get really ugly.

Tell that to the cargo doors of first gen airliners.

Tire wear can be estimated based on driving distance. Brake wear is less likely to be an issue if it’s electric - regenerative braking greatly reduces brake wear. Tire pressure is already covered with TPMS. It’s likely that each vehicle will have a cell modem on board, and can report things like a flat tire. I imagine there will be a few people doing maintenance on a fleet of cars.

I worry more about someone puking in the back seat, only for the next occupant to discover it - after it’s been sitting in a warm, sunny location for a few hours.

It’s like meeting really bad players in Descent

Brake pad wear sensors are already a thing, as is TPMS. Same goes for other sensors such as coolant an oil levels, and oil change intervals.

It will need to work like DEF sensors on modern diesel engines. You get a warning that counts down starting at 100 miles or so, then it’s either bricked or limited to 5mph until fixed.

The only difficult thing will be tire tread. It will be interesting to see how the AI handles that, as tires be have differently over their usable lifespan.

I’m sure that a high percentage of these HAVs will indeed be electric, so you may be onto something there about regen brakes. But unless they make stronger regen brake systems , regular brakes will still be necessary. And if it spends a lot of time using regen braking, you have to wonder if the regular brakes are getting enough exercise to still function properly in an emergency.. .

Thinks back to every maintenance-induced crash

Yes, imagine neglected aircraft...

Imagine millions and millions of them in the air over densely populated areas.

I was going to reply with “obligatory:” but I’d wager most of you have neither seen nor even heard of this film. oh well.

heck even the DC-10 had issues with that.

Whenever people talk about autonomous cars, I remind them that not everything is a perfectly square city with super bright markings, no potholes, and stable weather.

An autonomous car would be pretty much lost here. Even in the better planned roads I don’t think they’d work comfortably .

One thing that’ll likely help is, if driverless cars actually work and happen as predicted, they’ll be operated by transportation companies.

Sure, corners can and will be cut, but larger targets are easier to regulate (and I wouldn’t be surprised if regulation on maintenance procedures is done), and maintenance costs can be priced in (whereas for a driver with their own vehicle , fuel costs are the only immediately visible cost of a trip).

From what I've read, Regen braking can take a vehicle from speed down to about 5km/h, but mechanical brakes are still needed for a full stop or for potentially holding position while on a hill (I could be wrong on that though). So it's not like they don't still get regular use, but the amount of wear and tear is still considerably less.
