I have an accessory that sits in the passenger seat that lets me know my indicators are still on. Its a sometimes very useful accessory, it can also tell you when you are exceeding the speedlimit and if you are driving too reckless.
It has the ability to know what other drivers are going to do and also acts as a early warning device.
I sometimes forget to put this accessory in when I go for a drive and its then that I remember that I also have a radio in the car as I can hear a different sound to the usual static.
