True.
<< Since upshifts mean acceleration, they're almost always done in
circumstances where the way ahead is clear (if you're not sure if the
way ahead is clear, you shouldn't be upshifting, you should be braking).
For downshifts, the worst-case scenario where you get stuck in a
too-high gear is not a safety issue, it's a comfort-and-convenience
issue. ...<snip>>>
I think the comfort and convenience issues alone
make for a significant advantage for commuters and rec riders. But the safety
issues shouldn't be written
off. Eventually, having to take a hand off the bars
all the time to shift tends to become a factor in some
sort of incident. Not only does brifter shifting
keep both hands on the bars, it puts them on the
brake levers.

Track bikes are the weapon of choice
for cheap guys. Fixed gears are great
if you're too cheap to
buy brakes.
