I am, actually. I absolutely love what the Clean City law did to Sao Paulo

I’d rather they didn’t exist and I feel public transit shouldn’t be dependent on the whims of advertisers.

They operate at a loss so every extra dollar counts

The police also operate at a loss. Perhaps we should put ads on police cars?

…and we should absolutely not demand government operate for profit in any branch.

Also:

“We’ll continue our interview after you watch these ads.” (Straps the suspect to a chair in a Clockwork Orange fashion)

“No! Not that! Not ads! Let me just admit to everything, sir!”

Don't give 'em any ideas, please...

Excellent as thought experiment:

That's a good counterpoint, but to play devils advocate online ads seem to degrade user experience more than a static advert. Seeing a printed ad on the side of a bus doesn't make more hassle or slow me from getting from Point-A to Point-B while online pop-ups do.

Do those ads at all block/interfere with my ability to ride the bus/train? Do they use up (steal) my (artificially) limited public transit mileage (bandwidth/data-cap)? Do those ads track my bus/train trip and sell that info to other transit businesses? There's a pretty significant difference between those passive ads one sees (or ignores) on a bus or train and the sort of constant abusive behaviors we see from Internet advertisers.

I am.
