I agree, if one is managing to stay in the lanes. Crossing lines is, whether you are on something or not, reasonable cause to be pulled over. The officer does not know what you know. They only know what they can see, and a vehicle not staying within the lines may very well be driving too fast for the conditions, not paying attention or otherwise have impaired judgment, perhaps even due to ignorance.

I get that you want to be right. It's apparent because instead of having a discussion about what I am saying and asking me to clarify, you want to assume specific circumstances like 25 mph, or now the individual is just swerving slightly within the lanes rather than having real trouble staying within the lanes like I suggested.

The info I shared is defensive driving 101. I know to 'big man know how to drive don't need no safety' those classes seem like a joke, but it is useful material that is effective in reducing the odds of being "harassed" by officers, getting in an accident or losing control of a vehicle. It's not 100%, it's safer.

If a person does not do everything in their power (assuming no current know-how) to prevent 'x' (being pulled over for example) from occurring, then why are they whining? I have no sympathy for someone that teases the dog and gets bit.
