If they cant interact with emergency vehicles well, which they cannot, then they shouldnt be on the road. This is only one of the growing number of obvious reasons why...
There needs to be some enforcement and yes I would suggest suspension if it is found that the behavior is habitual for a driver.
A motorist wouldn't just be suspended, they would go to jail and have their car impounded. Actually, maybe it should be tow operators and not first responders with surprise driver privileges. We'll have 100% compliance real quick if those are the guys watching out.
The proposed solution is "We'll let you move the car." This is a reasonable "lose your business license" situation. It's pretty easy to sympathize with those who are "vandalizing robotaxis with blunt tools".
