From this little incident of biking today

Today when I was biking back from school, I biked on the sidewalk and carefully avoided effecting any walking people. At a cross, the traffic light was green so I cross the street with no fear. Suddenly, a car from my side was turning very fast, no slow down appearing to me and almost hit me. I was scared but then keep going. After a little while, the car reached me from behind, I guess the driver turned around and tried to catch me. He pulled over and told I lost my right to go straight cross the road when I bike on the sidewalk. I should yield to the cars that are turning. Since I didn't know the law of biking in Pennsylvania, I said thank you and thought he was right. Then we said blessing to each other and he left. After a little while, a young man asked me, apparently he overheard the conversation between me and the driver. He told me the driver was wrong and it is his responsibility to watch out for people on the sidewalk crossing the street when the light is green, no matter whether the people are on their legs or on bikes.

Haha, here is when I got confused. Because some people tell you this way and others tells you that way. And it was also striking me in a spiritual way. It's like the Lord saying to "do NOT follow people lest you are lost in the strays. only follow my word, cause it never changes." I know in the world everything is changing, even laws, even the world itself will perish, but the word of God will never change. How great is this assurance! How wonderful peace it set in my mind! We have something we can fully rely on from now to eternity. Also, the Lord says "Watch and pray". I guess today's incident is Lord's way to remind me to WATCH in order not to follow men but Him. Praise the Lord!

Btw, this is the PA biking laws and it doesn't say anything about crossing street and cars when biking on the sidewalk. But I found one article on Bicycle Safety titled "How to Not Get Hit by Cars", in which this is said:

Collision Type #3:

The Crosswalk Slam
You're riding on the sidewalk and cross the street at a crosswalk, and a car makes a right turn, right into you. Cars aren't expecting bikes in the crosswalk, so you have to be very careful to avoid this one. This collision is so common we've lost track of the number of people who've told us they were hit this way, such as Ray John Ray. One study showed that sidewalk-riding was twice as dangerous as road riding, and another study said it's even more dangerous than that.

How to avoid this collision:

1. Get a headlight. If you're riding at night, you should absolutely use a front headlight. It's required by law, anyway.

2. Slow down. Slow down enough that you're able to completely stop if necessary.

3. Don't ride on the sidewalk in the first place. Crossing between sidewalks can be a fairly dangerous maneuver. If you do it on the left-hand side of the street, you risk getting slammed as per the diagram. If you do it on the right-hand side of the street, you risk getting slammed by a car behind you that's turning right. You also risk getting hit by cars pulling out of parking lots or driveways. These kinds of accidents are hard to avoid, which is a compelling reason to not ride on the sidewalk in the first place.

And another reason not to ride on the sidewalk is that you're threatening to pedestrians. Your bike is as threatening to a pedestrian as a car is threatening to you. Finally, riding on the sidewalk is illegal in some places. (In Austin, those places are the Drag, and downtown on 6th St. and on Congress). If you do plan on riding on sidewalks, do it slowly and extra carefully, especially when crossing the street between two sidewalks.

Based on this article, I think at least from my part of responsibility, I should try to avoid biking on the side walk or at least stop and watch on every cross.
