Depends on the state. You must live in one of the relatively sane ones.
I live in Oklahoma, where it's either legal or not enforced. Tow trucks, construction vehicles, you name it. Blue lights everywhere. And not turquoise or some other "technically not blue" loophole color, but like "they bought their overhead lights from a cop car manufacturer and stuck it on their roof as is" solid fucking blue.
I’ve been asking why cars don’t have more obvious visual indicators since I was like 8 years old.
It’s pretty weird that we’re basically just working with 2 sets of lights and blinkers at this point.
For AV’s specifically, a pretty significant/obvious missed feature is some indicator that the car “sees” you. Pedestrians make eye contact with drivers to check if crossing is safe. How is there no equivalent for AV’s??? It’s such an obvious miss.

From a usability standpoint, you want to keep emergency signals simple and VERY consistent. Brake lights need to be a solid red for a very good reason.
On a similar theme, every time I get caught in stop and go traffic I wish we had tail lights that indicated letting off the gas. Like an orange light to say, "I'm no longer accelerating but I haven't applied the brake yet." I feel like everyone could coordinate traffic flow better with a little extra information, but I fear (much like these turquoise lights and adaptive cruise control) assholes will just game the system anyway to ruin everything.
I feel this is just painting a target on self driving cars for luddites.
If the autopilot without turquoise lights does something dumb, the driver is just another idiot, oh well. If the autopilot with turquoise lights does something dumb, all self driving cars are the devil.
Would light placement be better like... Idk.. Lit up license places, or wheel wells, or something? I guess not because some states already allow that stuff...
It's a genuine thought, but it is that as it stands, autopilot may behave erratically and it would be good to inform drivers both in front and to the rear. Emergency collision avoidance brake systems are already known to trigger at random
For something that requires far more complex decisions a special colour light in the rear can alert other drivers that various maneuvers could be taken automatically, such as a decision to change into your lane, normally or in an emergency.
I guess I'm not seeing it as being all that different from emergency collision avoidance systems in cars with drivers in terms of drivers behind them. I hate to be dense about this, but I'm just not seeing why any of those maneuvers would make a difference to the driver behind the car driving autonomously if it was being driven by a human or not. Don't you have to take the same actions regardless? I'm not suggesting Mercedes not do it. I'm sure people much smarter than me have figured out why this is important.
Maybe all cars with collision avoidance need to have these lights too?

So? They also brake suddenly when a kid runs out onto the road in front of them. Anyone following should have enough of a space cushion to get hard on the brakes and avoid hitting them. Or at least avoid hitting them very hard.
If you plough into them at speed, you'll push the stopped car forwards and kill the kid.
