kena a full power shutdown on my prius before - safety feature as engine was already running hot due to fauly electirc water pump.
disco lights came on with audible beeps
what the car did was GLIDE - this is what ALL cars (all ya, be it ICE, hybrid, EV) ought to comply
managed to bring it to a safe, off the emergency lane, stop
not a jam brake to complete stop like what this BYD "apparently" did
i use "apparently" as sometimes actual scenario can be misinterpreted.
highly doubt the tires came to a complete lock screeching on the tarmac, suspect there must have been some form of maneuverability to bring the vehicle to a safe stop.
maybe driver new to EV and panicked upon seeing there's no power at all
can be dangerous especially if one is on the right most lane, rain and in the dark - we know all too well how in broad daylight nonsense can happen anytime anywhere
you need to understand. unlike ICE and hybrid. EV dun have gears (gearbox and clutches). the electric motor drive the tyre directly in most cases. as soon as the motor lose power, it is essentially the tyre "spinning" the electric motor similar fashion to regen braking or engine braking(in ICE).. ya, it most likely not the brake from your disc/hydrolic brake, but still braking from the resistance of the electric motor spinning is still a lot if you moving at certain speed.
