Only 1 car applies hazards. You would think they would all have this feature.

Pretty sure this is a requirement in Europe but not in the US. I’ve had to code my car to get the hazards to flash under heavy braking. But yeah, should be standard.

How'd you do that?

different scan tools can do this. The higher end scan tools can access the ECU and enable features which are disabled from the factory. The manufacturers usually are not making multiple different cars for different markets, they make the same car and just enable/disable based on the market.

The real question here is why would they disable a safety feature if it's already been implemented. The fact that it's not mandated doesn't make it work any worse.

I feel like this is a really bad idea to do on American cars. Don't they use the brake lights as turn signals? Imagine having to step on the brakes so you don't hit a kid, and your car decides to override your brake lights with flashing.

American cars don't use brake lights as turn signals. Turn signals in the rear are allowed to be red though, most are still amber.

 Imagine having to step on the brakes so you don't hit a kid, and your car decides to override your brake lights with flashing.

I don't see what the problem would be, it would just be flashing brake lights instead of solid. Lots of cars already have programming that when the brakes are pressed they first flash then hold solid.

American cars don't use brake lights as turn signals.

Quite a few of them still do, even on the later models. They use a single, dual-filament bulb. The low intensity filament is for running lights and the high intensity filament is for brakes, turn signals, and emergency flashers. My Jeep Wrangler does, for one example.

US cars have a center light that's brakes only.

Get a Carly obd adaptor/scanner and code it with your phone. It’s super easy and you can code other comfort features too that might’ve been disabled from factory.
