Test driving a fossil fuel car

Linked below is a tongue-in-cheek test drive of a fossil fuel car, by a Swedish Tesla electric vehicle (EV) owner. Some of the humour may be lost if you aren’t familiar with EVs in general, or Teslas in particular, so a few points to note:

● it is not necessary to start a Tesla — sit in the driver’s seat with the “key” — select drive (which releases the hand brake) — go
● similarly, no need to turn a Tesla off — shift to park/engage hand brake, get out, lock — if preferred, let the Tesla lock itself
● EVs use the electric motor to generate electricity when the accelerator is released — this produces a braking effect — in the Tesla, the braking effect is quite strong & the brake lights are activated — use of the mechanical brakes is generally necessary only for coming to a complete stop, or in an emergency
● owners routinely charge their EVs overnight, at home, at little cost
Tesla have installed free-to-use, ultra-fast chargers (Superchagers) to facilitate cross-country travel
● electric motors have only one moving part, while fossil fuel engines have hundreds
● in practice, fossil fuel engines use approximately 20% of the energy in fuel to propel the vehicle — the remainder is lost as heat — EVs use approximately 90% of the energy in the battery to move the vehicle
Tesla sells its cars through Tesla-owned stores, rather than independently owned dealerships
