I average about 10mph or 16kph on my e-bike, and gets passed by routinely by 'normal' cyclists going faster than my pace. E-bike users do not necessarily ride faster; I use one to help with the many hills in my area, not to go fast. I don't think it'd be fair to force me to use roads and mingle with cars just because I use an e-bike.
My wife and I got electric bikes about 8 weeks ago and they have been great for running errands in lieu of single-occupancy car trips. We live near the Interurban Trail/Aurora and the e-bikes enable much easier access to a variety of stores, restaurants, and parks, which are not easily walkable. We now appreciate the nearby bike lanes and quiet streets for making longer trips to bigger parks or neighboring downtowns like Edmonds. We recently had wanted to return to Capitol Hill to enjoy a more walkable neighborhood, but so far bikeabilty has been an excellent substitute. Plus, in four years there will be a light rail station near us to offer yet another alternative to car trips. We feel lucky to have these options in our "suburban" location.
"If you look at it too hard all "truths" become false eventually"
My opinion is that many apathetic people become that way because of being treated unfairly (in their view) or feeling helpless, and way less people become that way because of thinking too hard.
"Or worse, change their position thanks to millions of dollars ..."
Well, I see new data: lobbying $$$ that could make a previously trusted politician biased. Time to update my simplistic model on his related political ads to being less likely to true. There might be another politician who changed positions based on new or emerging body of evidence - maybe this person is more trustworthy this time. New data -> updated evaluation.
"the masses believe the lie, doesn't it become the truth"
I'm not familiar with post-modernism or Stoicism. But I sure hope that the proportion of people who believe one thing does not ultimately determine its truthfulness. The way I would initially simplify this is to rely on the likely proportion of unbiased people who hold one position versus the opposite. And by unbiased, I simplify that by not trusting greedy people, or people who have not studied the policy or history of it or other places who've tried different approaches. I think these initial simplifications will already cut down many viewpoints and voices that I do not need hear, in order to make an informed voting decision.
Did the Christians try to convince the agnostic about something? If not, nothing changes before or after they leave.
Anyway, the OP was about political ads that can affect how people vote, a decision to vote or not affects the community. Being agnostic about something (aliens) does not necessarily have the same gravity of effect as believing in a political ad.
I think people should be more comfortable with non-binary truth, based on the likelihood that something is a lie or not based on historical record. I would put more trust in a statement from someone with a record of telling unbiased truth versus someone with a record of frequently spewing lies or having ingrained bias.
Otherwise, if you don't make these types of initial simplifications, it becomes too complicated to start evaluating the truth of any statement, including scientific ones. And it's okay to be make a mistaken evaluation, just reevaluate and adjust the simplified "truth" assessment model based on more recent data.
There is a danger in deferring a "truth" assessment: a community loses a sense of shared truth leading to polarization, doubt, confusion. And a so-called "neutral" person is, by not taking action, implicitly supporting the dominant narrative, which may be a lie after all.
