I have thought of this for a while. But, why has there never been a fully covered 2 wheeler / single seater on the market ? It seems like the kind of thing that can exploit the pros of a car, while mitigating atmospheric and safety related problems associated with bikes. I am genuinely surprised that there hasn't even been a startup that has tried to dabble in this, let alone an established company. My only guess focus groups might hate the idea of it. On topic: I welcome the push towards bikes as a primary method for transport. If the necessary traffic rule adjustments are made, then biking can be a very safe method for transportation on a daily basis
