in many areas you have diehards selling off their bikes simply due to idiot drivers like here in south florida...about 2 in 3 have no insurance and are not even citizens.
That is a risk we all take when riding. Some areas are worse because of idiot drivers/congestion, some areas are better. One probably has it best if they live out in the country somewhere. My dad who came here 20 years ago didn't buy a bike for 19 because he was afraid to ride in the city/surrounding areas, meanwhile he grew up on a motorcycle and rode like crazy back in Europe.
If you truly like it though you will ride no matter what area you live in. You guys in the US have it good anyways, and people in other countries only crave for what you have.
Here in Canada for example, having a Harley is a luxury and I haven't met one person yet my age that has a Harley. Insurance is INSANELY expensive, if you are under 25 you are paying anywhere from $ 2500-5000 per year for a bike. Bikes themselves cost more here, and if we want to get parts we generally get raped on taxes/duties because everything comes from the US anyways.
Or take Europe for example, very crazy drivers, a lot of mountains/turns, I would shit my pants if I had to ride my motorcycle in Poland or Italy, I'd probably get run off the road there. Also owning a Harley in Europe is like owning a Bentley here.
The US really is the land of the free when it comes to bikes, so enjoy if you can and don't pass it up. Also if you have the time/money take a big cross country tour, lifetime experience.
