I both agree and disagree with you. As a bike commuter in San Francisco, which is a much more bike friendly city than New York where I used to commute to Union Square from Park Slope, I definitely experience the "traffic too fast" thing. I am lucky to have an office now where I can store my bike in our office (we have dedicated bike parking inside on the 11th floor where our office is), but I also know that is rare. However, it does make it more likely that I'll ride to work (and do every day).
Regarding getting to work sweaty, why not ride slower? Sure, you might live in a hotter place than I do, but if you reduce your speed you'll sweat less. I think many of us on bikes are still getting out of the lead foot mentality of driving a car.
Traffic too fast can be controlled. Traffic too slow? That's one that can be solved by separated bike lanes. Look at the Netherlands and how they solve it. I personally hate the combined bike/traffic sections of Market St in San Francisco. Those are the most terrifying 7 blocks of my commute.
