Why is it necessary in pro bike racing to have all those support cars? With these expensive pro bikes being ultra reliable these days and the carbon footprint etc these following vehicles shouldn't be necessary. If they have a problem like a puncture or snapped chain they should have to fix it themselves at the roadside like we all have to. And another annoying thing is the riders being miked up to the support cars so in effect the riders become like radio controlled robots. Its time pro bike racing woke up and got into the 21st century.
