Apart from legal demand, why should a motorcyclist avoid driving in the center of the lane?

1. Because it annoys car drivers
2. Correct answer: Because the center of the lane is the dirtiest and most greasy part of a road.
3. He is not prohibited from driving in the center of a two-way roadway, or in the center of a marked lane within a two way roadway.
4. Because he should keep to the left and take account of other riders.

WhyThe middle of the lane is the dirtiest and greasiest part, where oil drips from cars. That is why a motorcycle should avoid it.
