Regardless of jurisdiction, it is less safe for bicycles to be on a sidewalk.
People keep saying this but would it be safer for a couple of parents taking their 5 year old and 7 year old out for a ride to be in the street than on the sidewalk?
Sometimes it is safer to be in the street than on a bike lane or sidewalk. Sometimes it is safer for the cyclist to be in the street.
I do a fair amount of riding and used to ride my bike the 15 mile one way trip to work somewhat regularly. I would take bike trails and bike lanes wherever they were available. There was one stretch of road where there was a hybrid two way bike path/sidewalk on one side of the road. It was quite safe when heading southbound, but when I headed northbound on it I was on the "wrong" side of the road so when all of the cars came up to the stop signs on the cross streets and prepared to turn right they would look left and never look right. They have a stop sign and are required to yield to both the sidewalk and the street traffic. I about got hit several times so I finally I started riding that stretch in the street. I could ride the 25 mph speed limit but would occasionally get yelled at to "Use the bike path!" Sorry, guy, that you are inconvienced to have to get five feet away from the curb to pass me when I am already going the speed limit.
That being said, I have yelled at my share of other cyclists when riding downtown in the city. There are many cyclist who feel that they do not have to follow the rules of the road and run red lights, go the wrong way on one way streets and even go in front of traffic that clearly has the right of way. They succeed in pissing off drivers that then drive aggressively at the majority of cyclists who are trying to do the right thing.
As far as stop signs go I try to be pragmatic about it. If there is no traffic, I will slow and be ready to stop then go carefully through the sign. If there is traffic coming that I will beat I will slow almost to a stop (nearly a track stand) and go so they don't have to wait longer while I have to get my bike started from a complete stop again. If the traffic will tie me or beat me to the intersection I will stop and wait for my turn. I also accept that my bending of these rules for pragmatism may result in my getting a ticket when I don't notice Johnny Law around and I accept that possibility. If I get busted for doing a complete track stand (full stop without putting a foot down) I will fight that ticket. I will bring my bike in to the court room if allowed and demonstrate the track stand to the judge. Some cops have interpreted a bicycle stop as requiring a foot down when not all cyclists need to put a foot down to come to a complete stop.
In Minneapolis they tried to pass an ordinance that would allow cyclists to stop and go when clear at all red lights. The rationale was that all cyclists are doing this anyway. First of all, not everyone is doing this. Second, many who are going through red lights aren't stopping. And third, many who are going through red lights aren't waiting for it to be fully clear. If cross traffic or turning traffic has to slow down or wait it isn't clear. They totally didn't think about oncoming traffic turning left who finally gets their green arrow but can't go because bikes are stopping and going through their red. It was a bad idea and I'm glad it didn't pass.
I know, I know, TL;DR.
