Well well well ... evidently a very closely-controlled and well-researched bit of study, matching like for like! No doubt peer-reviewed too.
I reckon, on a dash up the dual carriageway, a car would have beaten a bike. Pity, but that does appear to be a fact, no matter what.
Interesting bit about cup holders at the end.
My bike has a couple of cup-holders, of sorts. OK so they're really bottle-cages, but they serve the same purpose. On the other hand my
car has
nowhere to put a cup. Of course I don't drive a Merc and have no intention of ever driving one...
And as for keeping feet warm - well I have a couple of foot-warmers, myself. Others may call them socks, but they do the job...
