Brilliant. For once, quotes by critics say the truth. This is why I used to love Ben Elton. Acerbity and spot-on observations served up in a rapid-paced story that still has plot(s) and humanity. I don't think Tom Sharpe is funny or outrageous, and it seems that Elton is the only author/comic who still manages to outrage the Brits because nowhere is there mentioned the second crucial element (apart from car and road industries) that makes this book: the hero is a CP sufferer, or spastic. His introduction is so ingenious, as are those of several others, that this might be a spoiler, but I think not mentioning it at all is part of the prejudices that Elton and his Geoffrey fight. I really really like this young man. Every male UK author of the last decades features those thinnish, nerdish, uncool anti-heroes, from Fry and Laurie to Pratchett and Holt, but this Physics doctor with his genuine disability, that makes him overcome the oddest odds, is something I've never read the likes off.
The subchapters all have headings, making it more obvious that Elton could well deliver any of them as part of his stand-up routine(s), but just as those live-programmes always had threads and looped back and forth, this is a novel, not just a string of pithy socio-political observations. Humour is not just in puns and observations, but also e.g. in Deborah's parents.
I had stopped reading him a few years ago, when the novel Popcorn wasn't as good as the absolutely fantastic play. I had loved and still think Inconceivable ("Maybe Baby") is a masterpiece, but found nothing funny in his - still relevant - later works. This is his second novel, and I'm glad that my watching-Robson streak made me get over the cover and the age and get back to my Brits, they are the best.
ETA: after page 200 it gets a bit boring, but then in America, linguist Noam Chomsky and punk musician Jello Biafra make spoken word albums where they just talk about basic facts (stand-up is related to that and serves some of this function in other countries), because the media doesn't and the vast majority of people believe insane lies of those in power, ie. companies and corporations.
Elton does get back to the point though, and he never gives in to any simple black/white solutions; in fact mostly there are none. The good guys plans tend to not work, or nobody wants them to. In this case actually, history might have changed one factor: water isn't that much cheaper than oil.
ETA-TWO: what might surprise people who know Elton's brilliant work for Blackadder and other shows is that he mostly writes crime novels, and that he does breathtaking show-downs. Those usually bore me, esp. on a large scale, but in Gridlock Elton tightens the screws in the last 100 pages or so and never lets up, genuine twist and turns in a city that is completely disabled by the end. There are beautiful triumphs of those considered more disabled, but there's never a fictional happy end, because Elton treats real issues, and those are harsh, even in comedy.
