I don't think I'd like a full screen in a saloon taxi but I'd definitely have one in a miniwat. Maybe some sort of thing that clips on to the headrest would be more suitable for a saloon car. On a related note Mrs. Catcher showed me a Facebook post last week that made reference to the old flashing roof sign... basically telling folk that they should phone the Gardai if they see a flashing roof sign. I've long been a proponent of bringing it back so glad to see that someone agrees with me but I haven't heard anything about it as a driver e.g. who's installing them, etc...
