I swear the only thing worse than driving a truck is towing a horse float - where not only is your stopping distance huge, but your cargo will actively try to kill itself if you do anything unexpected*.
But yes, people who cut off trucks are fuckwits and deserve to have 20t of bullbar in their rear bumper.
* 'unexpected' things include:
- changing lanes
- indicating (flashing lights are scary, man)
- changing the radio station
