Valve lash would imply improper timing right? And the engine would sound rough i guess. But the engine would not even turn over, nothing would happen when I tried turning on the switch, ignition was on though and electronics would ve up, so like some electronic or safety system intervened.

Oh I didn’t realise that’s a possible sensor. I’ll try and test this more.

Well yeah i see the driver at fault, i was just explaining why people say the chick on the bike was also responsible for the accident

On crosswalks you tipically have to get off the bike so you give the cars longer time to see you. Crosswalks are for pedestrians, not bikes, so you have to walk the bike.
