Perhaps add something like this:
"As I was on the phone with Porsche's product expert, I was told the car need to be repeatedly filled with a liquid called 'gasoline', at one of their new 'gas stations'. When I started pouring gasoline into it, using an awkward and smelly mechanism, a display updated the price (which I was expected to pay immediately) faster than I could think. It quickly reached $20, and I wasn't ready to pay more than that. Given the average income around here, who in their right mind would pay more than that for a single trip? So I made sure to stop this, and pulled a big lever on the handle, but it kept dropping small amounts of gasoline, some of it on my shoes, which I could still smell hours later. Guess what, barely 90 miles later (I assure you I was driving less than 78.5 mph at least at one moment), the car started making funny noises and occasionally stuttered in its mechanical motion to a degree far above the usual vibrations it had all the time. Eventually it ceased functioning, but I could still drive off the highway and come to a stop. Porsche's product expert explained to me on the phone that it must have run out of gasoline, in spite of the horrendous amount I paid for it."
