Trade "in" standards

I was listening to the radio a couple of days ago and laughing at the adverts. All you get with radios in case there is those who don't understand, it is voices, so no pictures just some one very excited in your speakers. Well there was an advert for a car and the voice over came on get this beautiful car for only £200 a month with all these extras and it sounds good and he gives you this information and gets you hooked using 25% of there air time. The other 75% is another persons voice giving all the terms and conditions first payment of £1000 last payment of £2000 subject to checks blah blah. When we hear these adverts we laugh cause well its funny when we hear all the T and C's however it got me thinking on TV adverts its exactly the same. The TV shows a nice car with a price tag only £200 a month and its great but then in the bottom of the screen in small writing is the £1000 and £2000 payments and T and Cs. When I realised this I also thought hang on, why in TV adverts can they hide the facts in the bottom of the screen in small writing, that is the equivalent of the radio adverts doing the facts in a whisper. It should be the same if the radio have to do that Facts in a clear voice TV adverts should have to show the facts in a bigger type in the middle of the screen. I don't think that the standards are the same, if radio adverts were in distorted whispers we would be outraged and it would be changed so why not TV adverts with there small print?
