I live in Seattle and regularly ride through the city. I haven’t noticed a huge increase in traffic but notice there are way more Uber/Lyft/door dash types of cars on the road. These are the worst types of drivers and you really need to be aware of them. Their focus is not on driving safely. They will suddenly stop in the middle of the road, flip u-turns without notice, and have little regard to anything other than getting to their next job.
Regular drivers also exhibit a lot of these stupid habits. I see people stopping in the middle of the road or at lights, staring down at their phones, obviously looking at directions or something. Ebikes don’t bother me too much. I still pass most of them….except on the hills!
