All states should pass laws that allow for someone in a vehicle to drive through/over "protesters" deliberately impeding their freedom of movement on public roads. Blocking and surrounding a vehicle is clearly a threat to those inside.
The video below is from California so I'm guessing the driver will be investigated (possibly arrested) but the criminals in the road won't be.
If you live or travel in a democrat city carrying some sort of non lethal munitions for scenarios like this may not be a bad idea as well...
