Only if you've got a stupid racing bike with only hand brakes. Coaster/foot/back-pedal brakes are standard issue around these parts, and I wouldn't ever want to ride a bike without one.
Depends on how you ride. An adult in the US, you're on a road bike bent over the bars and going 15-20mph. Hands on the brakes at all times. I do a ride every summer with 20,000 like-minded people and if you see even one bike with coaster brakes all week its unusual.
I don't know if all 20,000 people are hard-core. Its just that road bikes are very, very common. Kids bikes might have coaster breaks, sure. But hardly anybody over 15 has one.
Brakes on rear wheels only are relatively ineffective, so I don't understand why you would prefer them. Unless there is such a thing as a front wheel pedal brake, which I have never heard of.
Rim brakes either grip too hard or not enough, and sometimes don't work very well in rain, and need regular maintenance and replacement. Coaster brake supplemented by hand brakes for emergency stops just feels safer and more in control in traffic situations.
