Sort of related, but an idea I had recently on a longer drive: I want a max speed control in my car. Not cruise control, I just want to be able to set the max s

  That sounds incredibly dangerous. What if you need a burst of acceleration in some emergency? Edit: Good points about the emergency cutoff being feasible, I stand corrected.

    Well, it's the inverse of cruise control. So some comparable way to disengage quickly like tapping on the brakes could be thought up I'm sure.

    How about have a point at which the pedal has extra resistance, and if you push through it, you can go over the limit?
    • IntronExon 9y ago
      That makes sense, and I’d pay for that feature.

      I'm pretty sure that the Volvo XC70 I rented two years ago had exactly this feature. If you'd kickdown it will release all the furious anger hidden beneath the hood.

        Every automatic does this, even a 1980's classic Mini has a kickdown cable. It basically forces the gearbox to shift down to one gear lower than it would normally do at the speed you are traveling at.

    These devices exist, and are quite common in some countries. The number of situations where you need to suddenly accelerate past the speed limit are few and far between, but in the case of the car I rented recently, there was a single tactile button for turning the whole feature off.

  I rented a campervan in New Zealand that had that feature. They called it a "programmable limiter". It was fantastic, I loved it. If I drive with the pedal to the metal, all the way down, then it works identically to cruise control. But you can also slow down for curves or traffic, and then resume your desired speed, without having to mess with any controls. I don't know if that was a new zealand thing, or a campervan thing. However from what I've googled, it's becoming a more common feature. https://www.buyacar.co.uk/cars/459/what-is-a-speed-limiter https://www.buyacar.co.uk/cars/459/what-is-a-speed-limiter

  This is a fairly common feature in many car models.

  That's a pretty normal feature on Mercedes.

  It would be nice if there was a little bit harder pressure section at the end of the pedal travel that disengaged it, so in situations where it's dangerous to be artificially limited in speed (such as overtaking another vehicle) there's an easy and intuitive way to disengage it that's normal behavior. Stomp on the pedal for speed and no limitation present, gently press until higher resistance section of pedal travel (which should feel a bit like the pedal being entirely depressed) and it works as advertised. I know Mercedes often have that extra resistance level, since I've relatives' Mercedes some (I don't know if it function in cruise control or speed limiting in any way). I always found it annoying, because it came with what felt like a lagged and softened engine response until you utilized it. That just made the cars feel like they had two modes when starting from a stop sign, too slow or too fast, depending on how hard you pressed. :/ Perhaps I would have adjusted better if I drove one for more than a couple days.

  That seems to be pretty common, I even rented a Nissan Qashqai here in Sweden that had it, not a fancy car at all.
