Came across this picture of a Cooper-Maserati driving - as you can see - on a public road.
I think the pilote is Maurice Trintignant (only because of the unusual headgear/beanie), so because of car and driver, it's possibly related to the US GP at Riverside in 1960.
Please correct me if you think you know better
Was this normal practice for GP cars to be driven on a public highway for a 'shakedown' run?
Anybody older than me know the story?
Cheers,
Glen
