Many of Valera's arguments seem highly dubious. First of all there is the cost factor. Valera CEO Robert Mackasek claims the $7,000 replacement cost of batteries was a factor. Given the infrequency with which hybrids need battery replacement and the success that vehicles like the Ford Escape Hybrid have had when used as cabs in Manhattan without battery service, this one is a non-starter. Mackasek also argues that clients don't actually want to give up the comforts of larger vehicles for smaller hybrids. This may well be true for many clients, but there are undoubtedly those who feel otherwise and it seems unlikely that even some small number of hybrids wouldn't be put to extensive use. Then there is the reality that most carbon offset programs are of highly questionable value anyway. It really just sounds like a bunch of excuses.
