They can 'advise' fans to park elsewhere and catch a bus, but if it proven there isn't a legal leg to stand on regarding actually stopping and enforcing 'no parking in residential areas' then people will do it.
Luckily I'm an away fan with almost certainly only one visit to the Amex to contend with next season, but I am probably typical of many away fans - I cannot abide being made to park and ride when I can find free on street parking a short walk away - you are supposed to park and ride at Southampton and Swansea if coming by car, and at Coventry and Reading only use official or nearby car parks, but I know of and always use nearby unrestricted streets for all of these because it is less hassle than hanging around and queuing for shuttle buses, and better than paying to park. About the only place I'd pay to use the official car park is the Reebok Stadium, because by car there is literally no alternative for miles in my experience. All the time there are alternatives, people will use them - at Old Trafford, people walk for 20-25 minutes after a game to get back to their cars, almost as far away as the Trafford Centre on occasions, rather than pay to park. People do not have limitless disposable income, so if there is a chance to save a few pounds, people will find the way and do it.
Away fans driving down from the North are even less likely to want to faff about with buses etc after 4-5 hours on the road, so you need to be honest and realistic here. Ultimately away fans are not interested in following guidelines like 'try to travel sustainably' or 'keep our neighbouring residents happy so we can get permission to extend the ground'.
