Question: your recommendation for note-leaving devices?
Backstory:
I think that one way to help the parking problem is through additional communication, such as leaving notes.
When I first ordered my S, I read much on TMC about parking etiquette. So I purchased an electronic erasable slate on Amazon, one of those things that have a battery that last for months, you write on it with a stylus and it holds that image forever, until you hit a master erase button. If I recall correctly, it also had a light so that the text could be read at night. (I've forgotten the name of the product & manufacturer.) My idea was that I would leave messages on it, e.g., "started charging @ time T, expect to finish at time T1, call me at my cell #XXX if there's a problem/emergency". I'd just use its magnetic backing so that I could leave it hanging on the car next to the charging port.
You see what an idiot I was, right?
Aluminum body. Magnetic slate.
Man, was I disappointed when that thing fell to the ground like a brick. Well, a slate-like brick. Disappointed and then quite shame-faced.
My Question: what would you recommend as a note-leaving device for this car? I don't want to use pen/pencil/paper because then it has to be taped somewhere. Something that can be seen at night as well as during the day. Maybe it could be left on top of the parcel shelf so that it would be visible through the rear window. It's also got to last a long time on a battery charge.
Thanks,
Alan
