I haven't seen anything like that on the highways of Ontario. Yet.

Jos, I absolutely agree with you about the advertising on and around British roundabouts. The roadsides are already so cluttered with buildings and overhanging brush that a foreign driver can't relax for even a split second for fear of missing crucial information. I remember with a shudder a particularly cramped roundabout in Wales that was not only under construction but also so plastered with billboards that I had a hard time finding the correct exit and consequently went around twice while both the satnav and my husband chuntered at me.

Senoufou, if Britain has traffic regulations to reduce distractions, I saw no evidence of them. For this Canadian, used to our literally wide open spaces, driving in England and Wales was one headache after another, all at top speed and often in foul weather.
