For 25 of the last 27 years I've worked shifts, mostly 12 hour day/nights but some early/late's too, at 17 different locations, 50% UK, 50% "overseas" (Germany and the Falklands) and at all of them I cycle commuted, sometimes only occasionally others 100% of the time.
Anyway, I can honestly say I slept so much better after getting off the bike than I ever did getting out of the car. Public transport isn't recommended, I fell asleep more than once and ended up going back from whence I came, lol... But, rather more scary ( to the older and wiser me) are the times I almost nodded off in the car, but I can remember no such moments on the bike....
