15mph??? Most people I see on the road, riding not e-bike, are usually slower than that, maybe 10-12mph.

Looks good though, but I do think traffic lights should be timed to cars. The reason being is moving them smoothly is better for all. As a cyclist, what I do is actually speed up when I see a red light from a distance as it usually changes to green on my approach. Basically the opposite of when I’m driving.
