Wow, it's amazing how much better the Subaru's automatic braking system is.

I worry that hitting a pedestrian at night is the most likely way I'd seriously hurt somebody, and I want to encourage automakers to prioritize the safety of pedestrians and other road users, so Subarus will be high on my list the next time I'm shopping for a car.

Subaru is just casually shipping better vision-only TACC than any other car company (I include tesla in this comparison, when just activating TACC) and nobody is paying attention to the fact that front radar is just not needed.

So all mainstream cars are vision only? No ranging like lidar?

Honda and Mazda use radar as well.

Just about everyone ships radar, not only for collision avoidance but adaptive cruise control.

Right, except for Subaru

How can it perform in fog/snow?

I've found that it appears to perform to the same level I can. In extreme precipitation it disables the system due to a complete lack of visibility and I don't blame it. However I've found this is very rare.

I'm not sure humans are a good standard:

Most cars use radar, Subaru does not

Subaru is going back and forth between vision-only and radar assisted, and also going through suppliers and project structures for EyeSight-branded systems. Current camera unit is supplied by Veoneer in Sweden, slightly older ones were outsourced to Hitachi Astemo, before that were mostly internal R&D and so on.

Current latest gen Subaru has a forward radar.

Subaru doesn't have forward radar except in the Solterra, which uses Toyota's system.

The 2025 models have 3 forward cameras, no radar.

They definitely have 4 corner radars and rear ultrasound. They indeed seem to have removed front long distance radar on Veoneer camera setups.

They don't mess with shipped cars and so they don't care about legacy compatibility, that makes it hard to keep track of changes

Sorry, yes they do have short range parking sensors on the front and back. I am referring to TACC/automatic braking sensors.
