Regardless of how good it may or may not be, until/unless roads are improved for cyclists and small vehicles like this Sinclair most people will be too afraid to share the road with cars, vans and trucks.
The best improvement recently has been cyclists wearing helmet cams. In London the Police do absolutely nothing if a cyclist is injured, and the courts give far lighter sentences if a motorist kills or injures a cyclist rather than a pedestrian.
Helmet cam evidence has now forced the Police to take action, and shown the Courts irrefutable evidence leading to some convictions and sensible sentences to aggressive and dangerous motorists. Drivers are slowly starting to realise they might get caught, and they will gradually learn to be more considerate, but sadly I think the time is still not right for mass cycling or small electric scooters in big numbers in cities like London.
