Exactly why Tesla switched to vision only
Nah, that was cost.
> People rediscover radar attack that has been known and fixed over six decades ago. Amazing. We've gone full circle now. I wonder if this is a problem of generational differences in knowledge transfer ... or rather the lack of it.
You can notice this in a lot of hardware products with "noob" mistakes that the prior product generation did not have etc. Software is probably the same but the product is too opaque to see into so ot just feels crappy.

>Shining intense light at drivers is also known to cause havoc and incidents. This is absolutely normal when driving on American roads at night these days.
Also, blue-tinted, blinding LED headlights everywhere, maybe that's what you meant. The laser lights maybe aren't blue-tinted but blinding nevertheless.
Oh, that Jeep was running red lights on the front. I thought that vehicle was heading away from me.
given car companies seem incapable of securing something as basic as a car key how long until smart 12 year olds can remotely hijack major car brands on a freeway with a laptop and a small python script?
Realistically, it's been possible on and off for quite some time. Chrysler's UConnect system received quite a bit of flak some years back over just how easy it was to take over full control of a vehicle[0]; not just locking/unlocking doors, but full control over the climate system and wipers, all the way up to starting and stopping the engine or changing gear in the transmission.

Did you know that fully analogue human-piloted cars are vulnerable? Researchers have recently described the "MadBrick attack": a malicious attacker can remotely disable a human-piloted car or cause it to veer off road by dropping a brick through the windshield from an overpass. Clearly, car manufacturers need to promptly address this class of vulnerabilities.
This has been addressed already, though not by manufacturers. If you live (or drive through) an area where brick attacks are known to happen, you just put protective films on the windshield. It usually still ends up damaged but you can continue to drive just fine (I know because I have).

My cousin got a new truck and he said everyone now flashes their lights at him but his lights are on low. His previous truck was fine but this new model is terrible. It's not just trucks it's cars too.
I'm ready to go to my member of parliament to ask WTF?

Why include a (much more expensive) FSD computer in every Tesla then, if it was just a cost-saving measure and radar is actually needed for self-driving? FSD works better today with vision only than any other solution with vison+radar.
Also, their original solution did sensor fusion with LIDAR, but the vendor find out and blew a gasket - because the LIDAR sensors weren't designed for safety-critical operation and to my understanding became a potential liability for the maker if they continued to supply them for incorrect use knowingly.

I think what's important here is not this first low-level stab at manipulating car radar systems. It makes a beach head on what adversaries can possibly do and demonstrates that manufacturers need to try harder.
I wonder how much effort is warranted though. If people want to mess up traffic they can drop a concrete block off an overpass, run a heavy chain across the road, change signage, use tire shredders or do any number of antisocial things. Many of which are extremely cheap and not preventable. Probably the most novel factor would be that sensor disruption is more deniable than many other threats to drivers. But how much…
There's another aspect to it: sure you could disrupt traffic with all the means you cited, but you had to be there physically, and you'd run the very likely risk of being caught and beaten up by angry drivers.
With invisible and electronic means like this, all it takes is to put a box with the jamming kit and a small battery near the road and you can trigger it when you're far, and you could even trigger it in many big roads at the same time and see the chaos you caused.
Why would you do that? For the same reason a few people send false bomb alerts for the police to evacuate places, and others SWAT streamers. Out of pure naughtiness.

I'm in Canada and any discussion I have everyone agrees how every damn car now has blindingly bright headlights. It's not the bluish ones it's pure white lights they're incredibly bright. Someone dropped the ball on the regulations for modern headlights. My cousin got a new truck and he said everyone now flashes their lights at him but his lights are on low. His previous truck was fine but this new model is terrible.…
There is some talk about regulating minimum projected area for a given amount of power to reduce this effect somewhat.

Really? It helps against a brick?
Similarly to glass with an embedded wire mesh.
