That's a good piece of tech, should be mandatory for trucks registered to work in the city.

Another safety tip for cyclists, cars and motorbikes: don't try to pass a right turning truck even if it looks like the driver is providing a gap to their right. They need that because the back wheels will take a shorter way around the curb, you don't want to be in the way there, which is an easy way for incidents like this to happen. Stay well back when approaching, or pass on the left.
