Nope, he means 70 mph (113 km/h), and yes, you just gotta pull out of a T junction and go; no merging lane, no on-ramp. That's a dual carriageway, characterised by two lanes and a central barrier (single carriageways are usually national speed limit, i.e. 60 mph). Bear in mind that as with everywhere else, most people are travelling 10 - 20 mph over the indicated speed limit (and thus probably travelling around 75-80 real mph). Underpowered automatics are death traps. That said I drive a BMW 330D (straight 6 3L diesel) manual, which probably would be fine as an automatic.

The idea of offloading software functions onto custom hardware built around a TTA is interesting - 5 years ago I used to work for Critical Blue who were writing software to design and build those custom processors and optimise an ISA for them. Worth a look.

www.privoxy.org - slightly more trouble to set up, but it rules on Windows and Linux. I usually set it up on a shared linux box and make it the proxy for my whole subnet.

After you have it running and tell your browser to use it (via network settings / proxies) you can configure it from the browser by hitting config.privoxy.org.

You will need to whitelist some sites (and specifically some edge caches for things like BBC streaming video to work), but it's usually not too hard. You can always bypass privoxy completely from the browser proxy settings, and it works for ANY browser (and things that aren't browsers but use IE for web access, like advert-loaded download "accelerators" should you be unfortunate enough to need to use one.
