Car personalities

Similar to those kids toys 'furbies', a device placed into a cars front and rear bumper so that cars can recognise other cars and communicate with them. The device would be situated on both the front and rear bumper, and a lcd screen would display messages. The messages would be totally random, and some thought put into the conversation, with the AI being advanced enough for the car to actually think what it communicates to other cars. For example, if you always park next to the same car at work, or you always pass a car going the other way on your way to work, the car would recognise this and maybe flash up on the LCD screen 'hi, how you doing? See you same time tomorrow'. Or, if its a new car in the car park, the car may come up with a cheesy line 'hello, come here often?'. A small sensor, similar to the ones some cars already have to detect rain and turn the wipers on, would also come into play, with the car saying to other cars 'nice weather we're having' or 'I wish this rain would stop'. The sensor would give out a signal signifying what language the car speaks in, so when replying, the other car could reply in the appropriate language. Also, the car would have a sex built into it, and again, a sensor would transmit this, therefore giving the chance of the car finding romance in the carpark or motorway. To us, the humble driver, it would enter us into the virtual world of car conversations and dating.
