"...the NTSB is recommendin​g measures leveraging new in-vehicle technologies that can limit or prohibit impaired drivers from operating their vehicles as well as technologies to prevent speeding. These include:

Requiring passive vehicle-integrated alcohol detection systems, advanced driver monitoring systems or a combination of the two that would be capable of preventing or limiting vehicle operation if it detects driver impairment by alcohol. The NTSB recommends that the National Highway Traffic Safety Administration require all new vehicles to be equipped with such systems.

​Incentivizing vehicle manufacturers and consumers to adopt intelligent speed adaptation systems that would prevent speed-related crashes. This is a reiteration of a previous NTSB recommendation to NHTSA."

In my younger years I would never have gone along with this recommendation. However, in current times it seems people are more interested in their phones than the skill of driving. Many people don't care if they speed recklessly. Speed limit signs seem to be a suggestion to be ignored.

Two people were killed in traffic accidents last week in Alcoa and Louisville. One was identified as road rage. He had his three children in the car with him and proceeded to run another driver off road resulting in the death of the other driver. The secondc accident involved an inebriated driver, passing cars on a two lane road, running a woman off the road resulting in her death.

Something needs to be done. Wouldn't it be interesting to have controls in your car to help prevent these issues. However, it could be really hard to merge into interstate traffic if you couldn't speed at least during the merge.
