I have an opinion as to why San Francisco Hertz cars received the parking brake warning light. This may be obvious to anyone familiar with that City, but a parking experience I had there made an impression on me.
San Francisco is a city with many hills (this becomes obvious to anyone watching the film Bullitt). Accordingly they have certain regulations regarding on street parking. These include what is known as "curbing your wheels", which is a requirement to turn the front wheels into the curb. Being an Easterner, how do I know this? Well, during a visit to SF following attending SAAC-6 in Monterey in 1981, I parked my rental car onstreet, facing uphill. I returned to find a ticket on the windshield for failure to curb the wheels.
So I suspect that engaging the parking brake was likely also a requirement. The light may have served as reminder to engage the brake, and /or disengage it when pulling out. The latter was important with the Shelby metallic brake lining, which does not become most effective until heated up. So Hertz may have wanted the light as a preemptive measure to remind customers what to do.
