The commercial options guess where you are in the tunnel based on crowdsource speed outside of the tunnel in both directions. When you come out of the tunnel you don't have GPS service but they will continue to guess until they reconnect which is a rather nice feature.

I have had organic maps freak out coming out of a tunnel and just never reconnect.

And it still might take a minute or two for your cellular to reconnect to gather further directions.

Some apps just might be better about the cellular reconnect side than others, I haven't tried them all.

Even then, it can take over a minute to reconnect to some cellular networks after a tunnel blackout, which may exceed the timeout of some mapping app data requests.

I hear ya, but it would have to be done with at least some form of red safety indicator, like..

"NO CONNECTION, LOCATION ESTIMATED"

On a side note, why don't Teslas obey the law that says not to stop in tunnels?

If I'm honest I'm actually wondering why none if those drivers were paying attention. Cars blow tyres or otherwise stop, it's not limited to misbehaving teslas. The tesla wasn't braking hard and suddenly, it just slowed down.

In my mind the drivers should have been paying more attention.

Sorry, I know we like to hate on teslas here. I still wouldn't buy one (or be a passenger).

Indeed you're right, the following drivers should have been paying more attention. Regardless, shit happens, whether it's a wet noodle or a dry chip controlling the vehicle.

How about a sideline test, send a half dozen electric vehicles through a tunnel, all on autopilot, and have the lead vehicle blow a tire. What would all the following vehicles on auto drive end up doing?

This is actually a perfect use case for a car controlling itself. Automatically applying emergency brakes is something cars (not just self driving cars) have been doing for a while now (in higher end cars).

The thing that puts me off a Tesla (other than the owned by a nazi who bought his way into government thing) is that the fatality rate is double the average, and the weird doors that unless you have been explicitly shown the emergency handle, you're trapped inside after an accident because the normal door opening latch loses power as part of requirements to not electrocute emergency personnel.

The Cybertruck is scarier, because the emergency personnel will struggle to break a window to get you out or use the jaws of life to cut you out on account of the armoured doors and bullet proof windows.

Sometimes, brakes are not the way.

Sometimes, steer the wheel hard left or right real quick to avoid a side impact.

I guess AI hasn't ever lived a day in the real world...

The benefit to cars auto braking is that cars can start braking a second before a person, with a much quicker reaction period. Plus we saw in your video how many people driving are paying attention 😅.

But this is not an argument for self driving, cars can and do have this function with the driver also paying attention for the best of both worlds.

I've been in a situation before where braking would have been the worst idea.

Like a split second later and I would have slammed into the side of the dude that backed out in front of me.

But I realized that very quickly and decided not to hit the brakes at all. I just quickly jerked my steering wheel to the left, which minimized the damages to the corners of our bumpers.

Ask AI to do that kind of maneuver on the fly and it'll totally fuck up, because AI doesn't actually know how to drive..

I'm being perfectly honest here, I tend to have very fast reaction time behind the wheel. But you're right, not everyone has fast reflexes in an emergency pinch like that.

Still, I'm not about to wait on the lag of computer chips and shit to just have to guess if the vehicle is going to respond the way I'm trying to control it.

I don't want lag, I want 100% realtime control.

Hell, I'm a nerd and I don't trust chips.

Edit/Addendum: I prefer older model vehicles that weren't built with spyware...

I love OSMand. It does exactly what a map should do. It doesn't have these weird user unfriendly quirks that Here and Google Maps have that make them harder to use.

I just have one problem with it, it gives some directions via notifications instead of voice, for some reason, which is baaaad when you're driving.
