^ It is one of the aspects of the Heinkel which in my opinion make it a small car rather than a "cabin scooter" or "cabin moped", that and good brakes!
Once I was in Deptford returning home from Bromley Pageant of Motoring with Squeak beside me. We were in the inside lane and a car to our right hid us from the view of a Morris Minor (in nice nick and possibly also returning from Bromley by another route) which was heading the other way.
Not realising we were there, Moggie turned Right in front of us, we were feet away and doing 20 mph, but I have very fast reactions and hit the brakes hard. Moggie had just spotted us and cleverly accelerated as fast as possible to try to make space for us behind him, I could hear his motor and tyres screaming. DUF's amazingly good braking and controllable handling saved the day. We were both hugely relieved not to have damaged each other's Pride and Joy! Squeak and I had both assumed we would die, but she was very calm then laughed it off.
