without a flashing light?

I'm looking out the window at a building site, there must be three of them on there, it looks like everything with wheels on site has a flashing light.

Do they seriously think that people don't look?

In other vehicle related news, the daft bus driver this morning nearly took the wing mirror off a cement lorry, nearly knocked a cyclist off her bike and stopped right in the middle of what should've been a yellow box all in the space of 30 seconds this morning.
