Relying on the vehicles sensors to warn of bicycles or even motorcycles is probably not the best policy. As a bicyclist I believe it is very important to ride as though I am a vehicle. Be visible and predictable. At the same time, I expect drivers to also be predictable and I will hold until I get the eye contact I need to ensure clear communication of intent by both. For either driver to not do that is an accident about to happen. That said, many bicyclists are bad behavers and that is a shame that makes us all look bad and puts many people at risk. Make certain as a driver that you understand the rolling stop rules for bicyclists at stop signs. Currently the following states have stop as yield laws for bicycles: Idaho, Delaware, Colorado (opt in), Arkansas, Oregon, Washington. The following states have legislation proposed in 2021: Virginia, New York, Colorado (making it statewide standard), California, Utah. The law sunsets in Delaware this year but may be extended. "Stop as yield" basically means that bicyclists can treat stop signs as yield signs just like we all learned back in drivers ed before we got our drivers licenses. To do that correctly though that means the bicyclist should be acting like a car in traffic and when it is their turn they can roll through the stop sign if it is clear. It doesn't apply to some yahoo riding on a sidewalk, against traffic, etc. However, if you hit and injure/kill that bad behaver the vehicle driver is going to still go through hell unfortunately.
