Last time I can remember was in Spain about four years ago, entered a single lane tunnel (well you could overtake a vehicle in it ) on a good straight road,Concentrating on the overtake I miss a warning sigh that the road curved right, leaving the tunnel at about 85mph ( I gave it some stick in the tunnel cause it sounded lovely) only to see the road disapear from view as it dropped away steeply with a chicane full of bollards and railings as the road crossed a river. Felt like a few boken ribs at the time and took about an hour before I could even get me leg over,the 450 mile bash home was a tad painful to say the least. Never did get to hospital to find out . Lessons learned Don't go into tunnels LEADING a ride out
