I hate that all the doors lock as soon as I start the engine with the door closed -- I have to hit the unlock button again to let hubby into the car. OTOH, I might need that "safety" feature some day, although it seems unlikely. The manual shows how to defeat it...
Mine just makes a little civilized beep and flashes the lights. Not good enough if you've forgotten where you parked. No antenna to tie surveyor's tape to either. I've thought of getting some orange plastic "racing stripes" to make it easier. Hey, it's the 'Sport' model with a spoiler, I'm entitled!
Worst was when I parked a rental car in the Vegas Costco lot and couldn't remember where I'd parked it or what it looked like. No, wait, the REAL worst was finding my daughter's forest-green Expedition (like
75% of the damn things) in the LA County Fair parking lot. Climbed light poles, etc. Ultimately we got lucky, but it took a LONG time.
