trip to europe

We recently returned from a trip through Europe. Noted the following:
1/ Most trucks are cabover, very few bonnetted vehicles seen.
2/ Only saw one vehicle with spider (demountable) rims - they were on a double decker open top bus in Vienna. The rest of the fleet had 10 studs.
3/ Single drive prime moves with triaxle trailers were popular, pins were setback further than in Aus, tri set further forward, probably good for manouvering the narrow streets.
4/ I listened hard but didn't hear ANY 2 stroke screamers on the streets

Cheers, from the oldb
