Trucks these days have to have more mirrors as a 1960's mod's scooter but there's still blind spots.
Yep, and we had sensors and cameras both sides and rear working in Central London, as more cyclists appeared the more things were added, the left turn speakers were ignored regularly, no matter how close you were to the kerb when turning left, they would try and squeeze up, leaning over scooting one foot along the pavement.
Not knowing when the lights would change and the truck may move.
You can only look in one place at a time, one or two mirrors on the same side together, or at a screen, that split second you were looking the other way some hero would dive into a small space, they even would hang on to the rear corner going up hills, it became just too much hassle and stress, 20 years ago there were no such problems in London. Everyone kept safe, there were lots of cyclists, not the numbers that appeared, and not the angry, get there at any cost types that appeared, it was like they were doing it, but not wanting to and dare you get in the way
My truck was involved in 2 deaths, with the grace of god not while I was driving it, after the second it was never put back on the road, no one wanted to drive it so it was broken for spares.
Remember just about everything you buy has been on a truck, they cost a fortune to run, and no driver goes to work looking to hit cyclists, just doing his job, keep away from the bloody things if you are cycling, one little mistake, on your part, the driver or a truck malfunction, a tyre blow out could kill you, the cyclist will be the one getting hurt or dying.
