Three are 8773 McDonald’s, though. :-)

It could have been a mistake. It does depend on where you are.
The best thing to do is download the GPS traces, turn off the data, and try and line up the traces to the roads. My bike rides usually go on both sides of the road, so I have a trace that will show the center of the road, and I usually have more than one trace per road.
If there are not many traces in your area, find a road that is away from most tall buildings (if possible), set your GPS receiver to record about every 1 - 2 seconds, and just go up and down the road several times. If there is a cross-road, go up and down that road several times too. That way you now have a '+' that you can use to align to the map. Don't be afraid to adjust the ways in OSM when you get more traces and can better average the data.
Also, even if the roads you added are not exactly correct, that is OK. In time you and others can adjust the data to make things better.
Good luck.

Yep. Shifting is a necessity here. Thanks.

It's probably already too late, but can't someone just delete him?
