You're daft. You can change it all you want but the people are going to see right through your pathetic attempts at subterfuge.
This is not about freedom of speech. You're free to say what you want. It's when you provide transportation based on this thinly veiled attempt to hide what you are doing that will land you in trouble. Your friends do not need you to advertise the service in the newspaper. Weasel your way around it, it won't work. You advertise and if you offer a ride to someone that you don't have an existing personal relationship with you're subjecting yourself to violations of whatever car service/taxi/commercial driving applies in your area.
I understand that people are smarter than that, they will see through it. That's not the point. The point is: is this legal? Does the law permit this? Perception of truth holds no grounds in court, in court we go by the law. In court I will have a lawyer and that lawyer will defend me and in court the judge must follow the law even if he or she disagrees just as judges must follow the drug laws even when they disagree. If I am free to say whatever I want then I can advertise this and not expect people to come by asking for a ride since I made no promise that I would. That's my right. I'm glad we agree on that. Like I said, if someone tells everyone that he or she sometimes eats at x restaurant then we cannot EXPECT that person to be eating at that restaurant at any given time. If someone says he or she drives around his or her friends sometimes then we cannot EXPECT that person to drive someone around just because they're friends.. Like I said, it's about freedom of speech. Are we free to tell the truth and not have someone say "You implied this"? I believe we are, I believe in freedom of speech.
I'm not providing transportation BASED on this add. That's what I'm trying to tell you and that's why this idea works. No one can prove that there is any connection. It's like driving down the road when suddenly you see someone on the sidewalk walking. You stop to chat and pretty soon you two are friends. Does that imply anything? I just want to hear it from you: does that imply anything about our intentions?
It doesn't matter that my friends don't need an advertisement in the paper, perception of truth does not matter to the written law. My friends WANT an advertisement in the paper and so since we have the freedom to speak freely I can do this.
Consider this analogy: the person who waits at traffic lights for cars to stop so that he or she can clean the windshield for them. There is no existing relationship and yet that person advertises that he or she will be at a certain traffic light at a certain time. Like I said, factual information. There's no mention of intention, just the fact that at x time that person will be at y location. And yet because of that people will make a point of driving to that traffic light to get their windshields wiped because they THINK (they don't know) that that person will be wiping windshields there. Is that legal?
I don't know what you mean by "existing personal relationship" because that implies that after the free ride we will stop being friends. That is false. The free ride is just one event in many that will occur during our new friendship.
I don't think the law can dictate who I'm allowed to be friends with.
