Re: WOW ! I thought I was on my own...
Personally I like coaster brakes and since I don't pedal but rarely, leg position at take off makes no difference since I don't change leg position Another way around the problem is to leave the coaster brake as it is (if you can get used to it) and add a rear rim brake, even just a caliper brake, or better yet a V brake. Then use a brake lever with a built in brake light switch. These levers are reasonable on ebay and are made for electric scooters. This route would give you additional braking power, never a bad thing.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
