In the UK the speed limit for goods vehicles is 10 mph below the limit for cars on motorways so there are plenty of vehicles driving below the limit.
The real risk is the opposite, cars bunched together at the same speed. This is where pileups occur, somebody at the front does something stupid and the people at the back end up colliding.
