HP,
Thanks for the comments, but if you actually bothered to read my comment you would notice that I said "No....NOT ME FIT IT"..."FIAT could fit a lap strap" as is fitted to millions of other car on our roads. There is an option for a 5th seat belt for the Panda. So there must be space. I just couldn't understand why not with the skydome or split seats. I now inderstand that there is no space between seats on split seats. Only an Idiot would try fitting seat belts without proper training.
And I started this thread because I dont want to drive dangerously or illegally. Thanks for your input about the law and dangers of lap belts HH, thats what I wanted to know. I definatly wont have more than two people in the back.
