Blind Spot Monitoring v2.0

While we wait for Level 4 or Level 5 autonomy, we need version 2.0 of blind spot monitoring. 

Without blind spot monitoring, you can adjust your mirrors so that you do not have blind spots, as recommended by the SAE, and detailed in this Car and Driver article.  Most new vehicles have some blind spot monitor, whether it's a sensor, a camera, coupled with an audio or visual cue.

This is all well and good when you are going straight.  The challenge is that in the few seconds between checking your mirrors, and then attempting to change lanes, another car may also be headed to the same lane you intended to go.  And then you narrowly miss the other car, or you go back to your original lane - either one would piss off drivers behind you.  Or worse, you cause an accident.

Or, you may be going straight and a car just starts moving towards you.  While according to this Wikipedia article, Nissan has some proactive capability, it's not widespread.

So, Blind Spot Monitoring 2.0 should have these features: As soon as you switch your turn signals on, and you are over a certain speed (meaning you are changing lanes), a better visual prompt, maybe a heads-up display or even just on the dashboard or the screen, that lets you know if it is clear.  

When you are in fact turning vs. changing lanes, it should be looking for pedestrians or bikers, and their velocity, and alert you if they are going towards you.

Finally, the sensors should be able to detect whether another car is moving towards you or going straight in its own lane and alert you to execute a safety maneuver.  I've seen a few accidents where two cars wanted to move to the same space in the middle lane, and neither seeing each other.
