From my understanding it's initially meant for use e.g. in slow moving traffic jams on highways. They're working towards getting it approved for up to 130kmh.

I'm guessing the feasibility of this is very city-dependent. in LA, the usual traffic pattern is "drive 60-70 mph for 20 seconds, slow down to 5 mph for 60 seconds, repeat". (Granted that that's because of poor drivers, it would be better to have a consistent speed of 30 mph, but there's nothing Mercedes can do about that either way.)

I don't see how 'approval' is required for _anything_. Not for lane-keeping at high speeds, and not for Mercedes to take liability for accidents while their technology is active at high speeds.

Luckily, the law disagrees in most countries and you need to get a type approval before you can sell a new car type or new assistive technologies. I would not want to live in world where this is not the case.
