Are V1 and V2 based on airspeed or based on a speedometer controlled by
landing gear wheels ?

If controlled by airspeed, the above poster has a pretty damm good point: how
come they would have been able to do the take off roll if their airspeed
indicators were inop ?

I was under the impression that reaching V1 and V2 speeds is a critical phase
of any takeoff. Is this really the case ?
