I rented a Ford something car from Hertz at the airport near South Bend Ind last month and what I got was a car with a compliance officer called "mykey". I've heard about cars with a key you can give to the kids that will restrict speed etc. and I guess that is what rental companies are doing.
To plug in my USB to charge and hear navigation on the speakers meant I had to install a phone app to subjugate my phone to the compliance officer software-not something I wanted to do in a rental nor pay for the cell data to download it. The car could do it but wouldn't let me do it. If I started moving it would not let me do anything. So I couldn't pair my phone when I get in the car. I figured this out after about 10 minutes of sitting in rental parking lot, then driving, stopping repeat. I needed nav.
So I had an AUX cable and I used the speaker jack as sound input to get navigation on the speakers and was sorry I did. First off I could not get music since you can't do radio input AND AUX. "No Radio for YOU". that took another 10 minutes while driving since messages were not clear.
Then I had to turn the volume up to hear Waze and it hit a volume limit and would not go higher. My hearing is not what it was so I had to look at the phone to see directions. Poorly thought out "safety feature" assuming volume is risk for everyone.
Finally with a speed Limit 70 open highways, so of course everyone is driving 76. But when you touch 75 there is a loud tone (not volume limited) and the main screen is taken over with a warning that you are nearing top speed. Not just once, it does it EVERY time you cross into 75 with which is so distracting. Speed then caps out at 80 even if you push your foot to the floor so it's like a mandated cruise control.
I can see this if you own the car and want to give your completely irresponsible nephew use of the car. But not for someone renting the full use of the car. I guess this is the future of car rental. I'll just Uber it from now on if I can't get a real car.
