I'd of reversed my "truck" up to her car and just sat with the revs at 3000 😃 I remember Top Gear drove an M3 and a Prius at the same speed over a given distance to prove the Prius produced more pollutants than the M3. I think the Prius only works at very low speeds.
Mythbusters the other night proved motorbikes kick out more pollutants than cars, that puts the governments Tax index up the spout.
