Amusing anecdote on mirrors.
I was driving yesterday and every time I thought of overtaking someone (yes, you can overtake people in a Traction), I looked in my small round mirror mounted on the door handle and there was this black car just poking its nose out behind me, looking like it was thinking of pulling out.
Check in the inside rear view and can’t see it but you can’t see everything in that mirror anyway.
Surely he couldn’t always be lurking behind me!
Then the penny dropped – I was seeing my door hinges.
