I think they should have it so there's a type of "slow down" light that supplements the brake light for when your deceleration is from taking your foot off the gas.
Perhaps a short paragraph of text elaborating on the driver's intentions
Risk Compension predicts that drivers would simply use this new information to drive more aggressively, negating any possible safety benefits.
The classic example we already have of this is when you are stopped at a side road about to enter the main road, and a car coming towards you on the main road signals to turn in.
Many people take the fact the other car has their turn signal on as a guarantee that it's safe to emerge, but any good driving instructor will tell you to wait until the car actually begins to turn before you yourself emerge.
They had their signal on but that doesn't mean they're actually going to DO what the signal said they would.
Same with the front brake light. It would be like "Well their front brake light came on, so I assumed it was safe to step into the crosswalk" NO. They could have just tapped the brake a second, doesn't mean they saw you, or they will actually stop.
I read the article and the next one comes up: "Mouse Sperm Structure Unveils Asthenozoospermia Mechanisms" and my co-worker was like wtf are you reading.
This is a most excellent place for technology news and articles.
