Assuming people would use those - totally! The risk is unfortunately that people just get them because they are free, and in the end are still driving cars for convenience. I guess one would need some system where the credit is earned via actual usage. You pay for it full price, but for ever ridden km you get credit. You already mentioned tax rebates, and those might indeed be a good way. However those already exist in countries for other kinds of commuting - e.g. if I commute by any kind of vehicle in germany I get a 30ct/km tax discount - whether it's a car or scooter. Picking a higher number for a vehicle which is cheaper to own doesn't really sound logical - but maybe just the marketing effect of it would drive adoption.
