Bread/potatoes are about 0.6g/kcal which would put the cyclist at ~30g/mile vs 100g for the car. Not that people live on that alone but with exercise you often have more potatoes with the steak etc.

I've been using an ebike which is one of the lowest emission things, and fun.

Someone here ran some numbers with bikes better than cars/busses including the cost of making them https://www.bikeradar.com/features/long-reads/cycling-enviro...
