Despite it probably being illegal, passing a car while staying in same lane sounds like a recipe for disaster but then just b/c i don't like tuna casserole doesn't mean you don't.
My question would be how much time would you save v/s risk? Only you can answer that.
I learned to ask that question when i finally i got caught speeding and the ticket was $280. Later i calculated the amount of time i would have saved by speeding v/s speed limit. Turned out to be 6 minutes; I rarely speed anymore and that is small beans compared to wrecking your bike; wrecking you life. I know the question wasn't about speeding but it does have a little to do with saving time.
Uhm, above is my long winded version of "evaluate and execute".
My 2 cents.
