Like all incentives, it should be on a sliding scale. Frankly, fall benefit would start to fall off after 100k income and/or some vehicle value cutoff, maybe 50

Like all incentives, it should be on a sliding scale. Frankly, fall benefit would start to fall off after 100k income and/or some vehicle value cutoff, maybe 50k. Beyond either value, you'd then decay to upper limits linearly (easier for the consumer to understand) with upper income level 160-180k range ish, and upper vehicle value maybe 100k. All numbers subject to change!
