This sounds like the way that jets refuel mid-flight. Works in the circumstances, but incredibly tricky, and requires zero interference.
Another option is solar panels on the car. The problem with charging while moving is the footprint. The car is just too small.
Even with 100% efficient solar panels, you're only looking at ~5kW power. Better than nothing, sure. But most people don't want to hobble around at 20MPH. And again, that's with 100% efficiency. Most panels are 15-18% efficient. Add to the fact that not all of the car is ever facing the perfect angle to the sun, and you're looking at like 500W power, tops.
It's certainly doable, but we need a massive change in perspective and driving habits to make it feasible. Also, don't expect to move a 2-ton car >5MPH with 500W.
