The Underlying Problem With A Neighborhood Electric Vehicle (NEV)

The underlying problem with a NEV as a street product is not the car. It is the driver. Why do we need to go faster than 50 km/h in the city? It's full of people on bicycles and cross walking. Besides, there is only ever 1 person in the car. What is safer, an NEV or a motorcycle? There is no mechanical reason that prohibits a NEV from going more then 40 km/h. It's always been interesting that motorcycles (which have no protective enclosure) can operate on any road and are relegated to the same speed restrictions as automobiles which have extensive (and regulated) safety features. It's also interesting that in both cases speed laws are set by government but the onus to operate the vehicle safely and within the speed limit is not set by the manufacturer before the vehicle leaves the factory, but is up to the vehicle operator. Why then would the operator of a NEV not be held to the same level of responsibility?
