one of the bigger deterring factors too is during winter season you are not allowed to ride your motorcycle at all as the winter tire regulation is in place (so from i think mid december to a date in spring)
and yes, i agree with previous posts that public transit is something people can fall back on all the time. and some work can get done. when i compare the costs in the
mid to longterm though, paying bike + insurance + maintenance + gear is still less expensive than my daily bus + go transit. god forbid the pricing if/when i have a 2nd car to get to the go station. so far, with one kid, we don't need 2 cars (knock on wood)
but the approximate 350 i pay monthly during the winter months on commuting is less than insurance and gas costs (+ convenience i get out of moto)
and if we look at it, let's be honest, if we look at the Canadian household debt, people don't "afford" a 2nd vehicle, they have the capacity to loan it out and that's it!
In the end as you mentioned a lot of factors go against the ownership of a motorcycle and that become the big deterrent to people owning them.
But if you put enough incentives, (low insurance, greener vehicle rebates -> fuel consumption wise, HOV) people are going to want to switch for the cost savings, and for the time savings.
But as it stands, the gov't doesn't have any interest in that obviously and most of us have a ...hmm.. grim outlook on what possibilities could be put in place to enhance our situation, hence, this thread lol
