RLJ (Red Light Jumping). (The definitive bikeradar thread)

A cyclist going through a windshield at 30 mph when the car bonnet takes the bike out from under them is going to harm everyone involved. Let alone the possibility of vehicles veering off the road or into other road users while avoiding the obstacle.

Yes, empirically it's clear more harm is done by motorists than cyclists but that's not going to change anyone's attitude. The risk of injury is similar. Cyclists RLJ blatantly. Drivers will give no quarter.

As I said RLJ is a bad thing.
