Yes . Your engine is turning in that case not because it is producing power by burning fuel but because the car's momentum drives the engine and not the other way around. Yup! As long as your clutch foot doesn't get tired of course . To each his own, really If you spend more time driving around KL around lunch hour or you just happen to be going through the Federal Highway at about 7pm-ish on a rainy Friday evening, I suspect you'd suddenly like automatics a lot more . Run your tyres at whatever your car manufacturer specs! The rating on the tyre is the maximum safe pressure it can handle. The car manufacturer however gives specific tyre pressures to take into account the weight and weight distribution of the car, suspension geometry and even the nature of a car (luxury vs. sport). Unfortunately, while most mechanics mean well they may not be familiar with the specifics of your car, and even then (as I'm sure we've all seen in the PC world!) many tend to follow anecdotal advice with no basis in fact. If you go racing then you might want to experiment with different tyre pressures to see how that affects your handling though .
