The downside: traffic. It's 3 lanes with no parking during the morning rush, and while there is plenty of room in the left two lanes, drivers get aggressive and honk/cut close when jumping in front of me. It's regular sidewalks on both sides of the road, but I'd prefer not to ride on the sidewalks: with the pedestrians and the ramps etc, my speed necessarily drops and I end up losing the speed advantage of the route.

Anyways, I end up just taking the off-road routes now. Takes a few mins longer, but is more enjoyable, and there's about 50m more climbing due to the up & down, resulting in better training and more calories burned.

If you have the option, I'd look into alternate routes that are more bike-friendly.

Out of curiosity - is the wide sidewalk designed for bikes? What I mean is, are there signs or painted bike logos on the pavement or something that indicate that bikes are welcome there? If so, I'd probably keep riding there and not worry too much about startling pedestrians; they should probably be paying more attention if they're walking on a bike route. If it's not marked and pedestrians aren't reasonably expected to be looking out for bikes, I'd probably avoid that route if possible.
