The dumbest thing a motorist said to me was when I was riding my e touring fat bike (North of $10k) with a $4k poodle on my back touring southern Ohio. This woman told me I should stop using drugs, smoking and drinking so I could get a job, get a driver's license, get a car and be able to live in an apartment like decent people do.
I busted out laughing and told her in beautiful English that she was terribly naive and should Google "Bicycle touring the United States". I said it was cheap and can be done for less than $250 per day. Imagine riding your electric bicycle coast to coast with your poodle for a mere $15,000. She looked like she had just eaten a crow.
