When airbags first came out, only expensive cars had them. I wouldn't be surprised if side airbags are still only found in nicer cars.

This seems entirely different though. It's more like hitchhiking. When you pay for an Uber or Lyft, there's a level of safety expectations in the car. When you pay for a black car, there's a higher level of expectations. When you don't pay anything, you are using it at your own peril. Now, this could be a bad business model or poor mousetrap for adoption. I'm not arguing with that.
