Given the number of tragic crashes that occur when truck drivers are not paying attention, and the horrifying number of people who die as a result, I think this technology should be made compulsory as quickly as possible, in all countries.
Meanwhile, if you happen to be stuck in traffic and see a large truck coming up behind you too fast, it’s time for prayers.
TIP: This is also a good reason to be in the lane next to the shoulder in a traffic jam so that you have a potential, last-ditch escape route — it could be vastly more important than trying to save a few minutes off your journey time!
Sadly, it is very common here in the N.E. USA, to see selfish drivers deliberately stay out in the middle- or left-lanes of a highway until they are alongside the exit they require then veer or even swerve sharply across the right-hand lane(s) to exit, right across the front of vehicles being driven correctly and safely.
