You have to remember that each episode is filmed over several months when it appears its all the same day. I ve been in Canada since the 1970 s and never driven a truck on this road but driven private car from montreal to Toronto several times . I find it quite stressful but not as stressful as my trips from heathrow to Coalville Leicestershire on the M1 ?M25 when my parents were alive. At least here there are multiple lanes I prefer highway through hell a bit more down to earth .
