As a side note does anyone else wonder why cars have such huge tyres today? Does a basic Ford Focus really need 215 section tyres all round? Consider that the S2 Elise was originally specified with 175 section front tyres (yes it's lighter but also much higher performing).
I think it's almost exclusively a style thing for most cars. Big wheels look nicer on the clay styling bucks and concept cars. Most cars in the US come with standard 16 or 17 inch tires anymore, even smaller (for us) cars like the Civic or Focus.
Aside from ride quality, one bad side effect that large wheels/tires have on performance is mud or snow traction. I've lived my entire life in snowy places, and the narrower tires found on cars from the 80s/90s do a much better job of cutting through snow and gripping whereas the fatter rubber you see today is more likely to spin uselessly.
I personally think that the style obsession with larger alloys and wider tyres has killed ride and handling in a lot of cars. I'm possibly in the market for a E46 M3 (as my Elise is going to be written off) and I'd prefer to buy one with the smaller, non-optional wheels as it'll ride and handle better...
P.S. Didn't you write off a Jag a few years ago? So far I've only totaled one car myself, but I've plenty of time to increase that tally...
Equally there are times when I'd miss the noise, a country lane, B road thrash for one, where the sound of the engine is more than just an aural accompaniment, and is of far more use than a rev-counter (an entirely pointless and superfluous instrument in modern motoring if ever there was one).
When lucky enough to be driving next to a hill, tall bank or in a heavily forested area (and in warm weather), I like to open all the windows and drop a gear sometimes to amplify the engine noise. My Subie is pretty buzzy though, you really need 6 or more cylinders in most cases to get a nice note.
I've done a few 2500-mile drives in my Forester, and countless 500-800 one-day trips. After a few hours the hum of that big 4-cylinder does get a bit incessant (the Forester is not a quiet car when cruising at 75mph on a highway crossing the Great Plains). On my last long trip I listened to a 20-some hour audio book version of Crime and Punishment. It wasn't much better than the engine.
I don't think it'll ever disappear entirely, but two, three, four hundred years in the future I can't imagine they'll be anything other than a curiosity.
Very possible, though I'll bet internal combustion engines will cling on in certain niche market for a very long time to come. But in a couple hundred years, people will look upon the gasoline auto engine the same way we look at early Boulton & Watt steam engines today.
