My reply was, in part, to a comment about driving across town. Walk or cycle or get public transport. Brighton has a huge congestion issue and it is in part the attitude of people like you and others which contributes to the issue. Think about your actions and their impact on others; otherwise the situation will get much worse.
More than a bit of an assumption there ! I go into town extremely rarely. If the council want to make it difficult and expensive to do so then I'm sure more people will follow me in only buying online or via out of town retail parks. It's not my fault if city centre businesses go under due to council policies.
