Earlier quoted context omitted.
I have an electric _bicycle_ that routinely dusts off ICE cars at stop lights. It just takes a while for all that machinery to start rolling.
I have a pedal-powered bicycle that dusts ICE cars at stop lights. For, like, 5 metres... Not only does it take a while to get all that machinery rolling, doing it quickly kills your gas mileage. Most drivers aren't drag-racing out of the stoplights.
I've noticed that too. I'm no athlete, but I can often beat cars across an intersection. Another thing I've noticed is that many cyclists don't shift down before they stop. They have to get up off their seat to even start. Even people in full kit on expensive bicycles do this.
