"Cycling in the middle of the road" from motoring.co.uk

Drivers seat is beside the passenger seat, rather than in-line.

It's a counterpoint to "cyclists take up too much space on the road" - if two cyclists riding two abreast are taking up too much, then every single car is doing the same thing all the time.

He neglects to mention that many drivers carry spare sofas around with them much of the time, too.

Well it's obvious when you put it like that. Thanks you lot.
