Sounds like a fascinating idea, but remembering how many mad men I say driving like crazy every day, I nevertheless have doubts that this could be anything else than just an extremely bad idea. Putting an azz who drives 180 km/h on the Autobahn and approaches your car to less than a meter with signalling lights behind the controls of an electric glider is not something that really gives you any peace of mind at all. If I would have a word in it, I estimate that around 5% of all car drivers and 20-25% of all bike riders in Germany would see their driving licences taken away immediately.
