...The only thing i sometimes find is it does take a lot more thought and concentration and so sometimes if i am feeling lazy or not in the mood ill be a little more 'relaxed' but its nice to know i have it in the locker as and when! Dunno if anyone else does this too! 
It does take more concentration to start with, but if you do it all the time, it becomes second nature and you'll start to do it without thinking. When I first started my training, I'd get home totally knackered! Now, I don't feel tired at all. It's like anything, if you practice at it, it becomes second nature to you after a while.
Also, don't get me wrong, I'm not saying you should use Heel and Toe on the roads because like you quite rightly point out, preparing for a bend is more about getting the right speed and gear before getting to the corner. So many people I follow seem to be doing all of the work right on the bend, leaving it to the last minute. When I get to a bend all I want to do is steer! Heel and Toe is useful if you get it a bit late and need to break and gear change. Again it's a useful tool to have in the box.
When you next go out and drive, try this:
- Get yourself set up for the bend (you're technique sounds spot on), in terms of speed and gear.
- When you're on the bend, apply a tiny amount of throttle. Not so that you're on the power and pulling out of the corner, but just a touch so that you're still applying a bit of gas.
What will happen is that the car will all of a sudden feel planted. There will be less roll and lean in the car and you'll feel as if you're cornering really flat.

I also know that following the types of drivers who brake on every corner or when another car passes them (I had one of those the other day) can be really annoying, but you've got to tell yourself that they probably haven't had any other form of instruction or tried to learn about improving their driving since they passed their test.
I generally hold back from them, wait for the right moment and just bimble past them. I've had people flash me in the past as I've trundled by, probably because they don't like being overtaken or because they think it's dangerous. Problem is, they're just not looking ahead. If you can catch a good cross view on a road and you know it's clear, it's very easy to overtake and you don't even need a fast car to do it. Like I said before, it's the drivers whose vision ends at the end of their bonnets who are the real dangers on the road!
Finally I always drive with my lights on. I find that people are more aware when they see be coming up behind them and this normally works in my advantage because once they know I'm there, they don't get a surprise when I nip past them
