In the past, laminated glass was usually installed in the windshield, with side and rear windows being tempered only.

The difference is that tempered glass is per-stressed so that when it cracks, it shatters into many tiny and dull pieces. Laminated is the same thing, but with layers of plastic sandwiched with layers of tempered glass. Laminated glass will still shatter, but will be held together by the plastic layers.

In an emergency, small improvised, or purpose built tools meant to shatter tempered glass will be useless if the glass is laminated.

    By default, Teslas are set in “one pedal driving” mode, which makes it so that the wheels won’t turn without the throttle/accelerator being pressed. That’s a different interface and behavior from the traditional automatic transmission, where simply lifting the foot off the brake pedal allows the vehicle to roll either forward or backward, depending on whether it’s in D or R.

    The selection of the “transmission” setting of P R D in a Tesla also doesn’t have tactile feedback that subtly communicates which direction it’s set to.

    The combination of the two means that the car is different in these ways and can contribute to mistaken gear selection plus application of the throttle, compared to a typical car.

      i felt more than a little sick to my stomach at “one pedal driving”.

        Have you tried one pedal driving?

        • I found it very easy to get used to the concept - it’s similar to taking your foot off the gas to coast up to a light but greatly exaggerated
        • the hard part was driving smoothly, just what I was afraid of. Take your foot off the accelerator a couple hundred feet back expecting to coast to the light and come to an abrupt stop. Oops.
        • it took some practice for me to drive smoothly with it, but also exploring the relevant config options. I do best with “creep”: mimicking automatics at very low speed but one ideal driving at all other times

          honestly, i can barely tolerate two pedal driving, but the thought of just removing the ability to actively brake in an emergency seems profoundly short sighted and dangerous.

            It doesn’t do that. I don’t think there is any vehicle that actually has only one pedal. There’s still a brake you can use any time.

            One pedal driving simply means the accelerator also slows the car as you let it up, so you may only need that one pedal on a lot of driving. This also means that standard brake pads and calipers can last much longer, since they don’t need to be used as often

            This is popular in electric vehicles because regenerative braking makes it convenient.

            • As you speed up, the battery feeds power to the motor to accelerate.
            • As you slow down the motor drags on your forward motion, generating electricity to feed back into the battery

            While you could have the brake pedal do both braking and regen, now you’d be adding complexity to the braking system, making it less reliable

            Edit: my car is set for very aggressive regen, so I rarely use my brakes. If I take my foot off the accelerator, it will come to a full stop fairly quickly. That’s one pedal driving. However it also has a standard brake and you better believe I’m using that as I’m waiiting at a traffic light or someone cuts me off or I mistime the regen

      Ahh, no. Plenty of automatic vehicles will either not move or move very slowly when idling in drive, and you will always need to accelerate if you’re facing uphill.

      It definitely sounds like the driver was at least partially to blame.
