If you don't play you can't win. I don't currently commute by bicycle but I emailed my HR department asking them if we could instate a commuter reimbursement program based on this new legislation. It is not real exact about how frequently I'd have to ride in to qualify, but if I could get my employer and ultimately Uncle Sam to pay for tubes, chain lube, and the occasional tire I'd be willing to ride in at least a few days a month.
I'm working on a "form letter" that others could fill out and send to their HR departments if they are interested in implementing this new legislation at their company.
