If you change into the left lane when there is insufficient room to do so, while standing on the brakes ... you are not pulling over, you are causing a wreck. Hope your insurance is paid up.

IMO cars should be very very good at what they try to do, and not pretend to do anything more. Tesla has way too many flaky features (that customers have to pay for) for a product that can kill people. I'm fine with what Waymo and Cruise are trying to do where the car is expected to never make dangerous mistakes in the circumstances it will run (with consequences for the company), but Tesla's target of doing everything fine most of the time but still doing stupid stuff frequently is not OK.

Because you get ample notification for when your car is about to fail.

So you can switch on your hazard lights, gradually slow, let cars past and then pull over.

No normal, competent driver would act like this incident.

If you're pulling over into the left lane, you're a moron and going to cause accident.

hazard lights, or turn signal seem missing. You'd generally want to move over to the shoulder. Emergencies definitely do happen but parking, in the fast lane, in the tunnel is _incredibly_ dangerous.

Because a computer was driving.
