Camera to identifying the optimal lane in traffic jams (periscope for cars)

English

You drive on the road and there is a traffic jam, sometimes the right lane is faster and sometimes the left lane is faster and you do not know which lane to choose (and it is clear that according to Murphy's Law You will be in the slower lane)

Sometimes the reason for the traffic jam is a car that stuck in one lane, but you do not see the stuck vehicle, other vehicles conceal that for you, and if you could see it you will be able choose the faster lane. (Sometimes one lane is faster for a short time and it is misleading)

So I suggest that someone will invent a camera on a stick or on antenna that can be raised above the car, and see what happens down the road, something like a modern periscope.
