Re: becoming worried
I think by the time they ever get around to regulating gas bikes away, if they ever do, it will probably be a moot point by then, because most people will have already moved away from gas bikes on their own accord.
I'm a prime example, I was always a big proponent of gas bikes until I discovered the superiority of electric bikes. Up until recently there were a lot of drawbacks to electric bikes, but now one by one they're disappearing. Soon there won't be any reason to regulate gas bikes away, because there just won't be enough of them to worry about, assuming there ever was anyway. Bottom line, I think gas bikes will disappear, but when it happens, it will probably be voluntary.
