Although this is a clip on the BMC of the fifties the tests were done on the german autobahn.

As you watch you will see ovals and splitty beetles

Hope you enjoy

Bloody cheeky pulling up at a servo then filling the tank from your own fuel can!
I never knew they made Morris Minors and Austin A30's in left hand drive, or would these have been made specifically for the tests?
