I would like to thank Wayne Martineau for raising the concern of vehicle tail pipes producing smog and poor air quality. Wayne and others can correct this problem by choosing to drive electric vehicles (EVs).
EVs have no tail pipe, emit no fine particulate matter, emit no chemical fumes, emit way less greenhouse gases and emit way less medium size particulates (as the brake shoes wear down slower due to the regenerative breaking).
In addition, the cost of fuel to drive an EV is about 80 per cent less than the cost of fuel to drive a gas or diesel vehicle, compared to a 30 mpg vehicle. I have saved $8,000 since we started driving our EVs.
