Tesla recently announced that they will update the headlights on the Model 3 & Model Y in the first quarter of 2021. The new headlights have a different light pattern and are more adjustable than the previous iteration. The ability for owners to set their headlight height up or down, as to not blind other drivers when driving at night has been a very well received addition by Tesla owners, and the new headlight design allows for a more precise focus of the beams. This video shows the differences between the new headlights and the current headlights. There has also been some speculation that the new hardware could unlock more possibilities for software involving the headlights. One example of this could be a feature that automatically adjusts the height of the beams depending on surrounding traffic.
In 2016, the NHTSA announced that by 2022, all new cars sold in the US will be required to have an automatic emergency braking system (AEB). AEB is a driver assist system that will automatically brake if either a camera or radar system on the car detects an object in front of the car that the driver is not braking for. So far, Tesla and Volvo are the only two car manufacturers to have met this requirement to completion. This is just yet another example of how Tesla being so ahead of the curve as far as automatic driving systems has helped them to meet regulations ahead of time, whereas other manufacturers will have to make changes in order to meet the constantly updating regulations.
