Since the OP will argue, I made this picture just for you.

1. Blinker from van was clearly turned on showing his intention to TURN INTO A ROAD WITH NO TRAFFIC. Check

2. Enough clearing for van to proceed turning INTO his intended direction without blocking traffic.  Check

3. Decision OP made? Move into box and block everyone, and you're accusing him of being the road bully?

If the van drive is a road bully then you sir, are clearly a road moron.
