  Disclaimer: I don't drive a Tesla. That being said, you really don't want to accelerate forwards quickly because you'll shred tires, and you don't really want to "decelerate" hard either because it's not good for your brake lifetime and passengers don't really enjoy it much. Electric cars with regeneration are more efficient than ICE vehicles, especially in stop-and-go traffic because when you don't need the power, it's not being used. Most gas vehicles still burn fuel spinning the engine while idling at a stop sign. So while yes, the acceleration may be faster, the real thing that's gained here is efficiency, because you can recapture some of the car's energy whrn stopping the vehicle.

    Hard braking isn't good for the front tires, either. Many vans are rear-wheel drive so hard acceleration wears the rear tires faster.

    One thing Tesla drivers keep saying is that they hardly ever need to break. Just lifting foot from gas pedal is usually enough. So brakes should have longer lifetime.

      Probably not much different from a car with a manual transmission (especially diesels), where the engine does most of the braking. The brakes on my mk4 VW Jetta TDI easily lasted more than four years[1], and even then only because corrosion killed them[2]. So I don't expect there to be much savings there. [1] The original clutch was changed at 450000 km. [2] The brake pads separated from the backing, even though they were only half-worn. Higher-quality pads might have prevented this, but the previous owner installed them.

  The regenerative braking only works for light braking. After that it's standard disc brakes. And I don't think flooring it off the line at every block through a residential area is a very safe idea, please don't encourage anyone.

    It's sufficient for nearly all city braking in my experience, sometimes with a little extra planning required, and with the exception of certain emergency braking situations. The only time I generally had to use the brakes were to completely stop below around 4 mph (6 km/h). On a Tesla the brake pedal only activates the standard disc brakes so you know when you're using them.

  >They can also probably deliver more packages per hour with how fast electric cars can speed up and regeneratively decelerate through stop signs and delivery destinations. Is this sarcasm??? Do you honestly think that regenerative braking is harder/faster than brakes? Are you the type of person that is hard accelerating from every stop sign in the suburbs?
  • mrep 7y ago
    No, harder and faster than coasting to a stop. Granted, full coasting to a stop really only makes sense for red lights but I'm assuming delivery drivers are doing some coasting when coming up to stop signs/yields which is what I do.

    > hard accelerating from every stop sign in the suburbs? If you want to deliver lots of packages without violating traffic laws, then rapid acceleration seems like obvious low-hanging fruit. If the vehicle is quiet and nobody's in the way, then what is the problem?

      >then rapid acceleration seems like obvious low-hanging fruit It's energy intensive.
      • p1mrx 7y ago
        Acceleration is power intensive, not necessarily energy intensive. You need (1/2)mv^2 to reach a given velocity, regardless of how much time is spent. If rapid acceleration happens to be less efficient, then that's just an engineering problem.
