History, and several decades of experimentation and tuning development to eke out exactly the most pleasing sound from an ICE engine, while electric cars that are loud enough to make noise have had, what, 6 or 7 years?  Since Formula E kicked off?

Almost certainly straight cut gears. If LMP1 cars used EV powertrains, they’d sound just like this. 

I’d wager the whine from this thing is due to straight cut gears.  They’re stronger than helical cut gears but really noisy. 

If the worst thing you have to say about a 1,400 HP vehicle is “it doesn’t have the good sounds,” we’re making progress. Would you be willing to sacrifice the soundz for an easily accessible 1,400 HP?

Car and Driver says differently.

I saw a video with someone explaining that the noise the car makes comes through a military grade speaker. It can make whatever noise you want it to make.

As a person with a fleet of RC vehicles, this is a familiar sound. Hearing it in the context of a full size performance vehicle makes me giggle. It’s been a long time now that nitro RC cars gave up the mainstream to electrics which are better in.. every way except the smell. They are unholy fast and I can’t wait till…

I dig it. A screaming car is a screaming car, be it a high-flowing ICE at redline or the crazy whine of seven electric motors. When you hear it, you know the thing is a beast!

Not sure how the military specs a speaker, but this theory has many more flaws than just that...

A military grade speaker? I’m gonna say that’s a no.

You want to point to an engine that makes some of the sweetest sounds on the planet, that would be the big block 440 under the hood of my Charger. When you’re just cruising and the block is burbling, the sound is almost soothing. Then you put your foot in it and the 440 roars...god, it’s so amazing. So undeniably cool.

They recently enabled traffic cone recognition on my Model 3, even though I don’t have the upgraded computer, and it sees all sorts of things as cones now. Pretty much anything small and orange/red off the side of the road is a cone now.

Stereo cameras should do this just fine. Humans don’t use LIDAR nor do they generally need to.

What’s maddening about that whole situation isn’t that Tesla chose not to use it, it’s that Musk posed it as some sort of negative. “LiDAR is for losers”, not “We think we can do it without the expensive LiDAR hardware that would drive our cars’ costs too high for the average consumer”.

Not so much that people might suddenly put fake stop signs all over the place, but more that AI systems can be easily fooled into false negatives. If a small decal or sticker could prevent a car from recognizing stop signs, imagine the chaos that could ensue.

And I think you are overestimating how the fuck you would do this.

Why would I stop for a cardboard cutout? I have two eyeballs, and therefore a sense of depth of field.  A cardboard cutout doesn’t look like a person with depth perception.

That decision not to include LIDAR, which could inform the car that sign is hundreds of yards away and far more elevated than allowable for a stop sign is paying off nicely.
