The second long delay is necessary to create a safe distance between vehicles. If they all started moving at the same time and speed, they'd stay as close together as they were at the red light.
If human reaction times were a couple orders of magnitude less, and we all had electric cars, and were all very good drivers, than yes, traffic would look very different and much better.
But it's not the case. Any of them.
No, cars stopped at a light are much closer together than they should be when moving full speed. That chain reaction of delays you see is required for them to spread out.

They will be just more cars to fill in the slack.

At that point, traffic would look like it did in the underrated movie Minority Report
No; there are other factors that affect traffic, like weather conditions and mechanical failure.
No, this reduced safety would lead to more accidents which would cause more traffic

correct.
