I found out the hard way that my car has an alarm. I was waiting for my kid and fell asleep in the car. I had locked the door so no one would nab me while I slept. My kid showed up, so I opened the door to get out and the alarm went off. Surprise!
I have also learned that the car has a huge blind spot and no one seems to be able to see the bright red car when they change lanes. I have to really be hyper aware when I’m driving. I have to duck quite often.
