They don't even necessarily have higher construction costs. Take a look at a mini-roundabout. It consists of a slightly raised section of road (low enough to drive directly over if need be), so the comparison there is road + lights vs road + slight hump.

Here in Europe, the vast majority have a manual gearbox, but maybe that's because we actually like to drive cars. Never understood why, in the "land of the car" you want to neuter the driving experience.

Flawed argument - if imports are cheaper, stopping local produce from competing, and transport costs rise, making imports more expensive, and you now start buying the (previously) more expensive local food, how has your food cost not risen? That is without adding the additional local costs from fuel prices (transport to market, transport of fertilizers etc, heating, lighting and so on).

Try $7.76 per (US) gallon. That's about what we pay in the UK at the moment (£1.30/litre).

No, but I work in IT and know how to ensure that I am not being misled. Now look at it the other way round, you call a hotel to book a room, they tell you it will be 5 star, have a TV, en-suite, king size bed, etc. etc. Now when you get to the hotel to use the facility, it's nothing like you were told - is it your fault for not checking (in person) that the room is suitable *before you turn up to use it*?
