I believe its ctrl+tab, don't hold me to that though. 
How is it unexpected? I don't know about you but I watch how people are going to pass me, so I can setup a counter-attack. And if he isn't pulling out to pass, this can only mean two things, hes going to draft me, or bump me. I'll be prepared for either one.
Can you share your definition of bump drafting? I just want to make sure we are talking about the samething here.

Yea, that's really working for Kyle. In the last 749 races he entered, hes won 8.
Bump Drafting wouldn't be so bad in NASCAR if it wasn't for the aero package / restrictor plate combo. They just can't afford to let off the gas, which causes a lot of accidents. Who is to blame?
Yes I understand that, but it still doesn't keep a driver from bump drafting. There are just so many situations that bump drafting can benefit the drivers that are doing it, it’s not really worth getting into it. I just used that one as an example for my argument.
Should have added: If it was a head to head race, obviously the better driver would win. But as many of us know, the best driver doesn't always win the race. Sometimes it's the better team.
Edit: forgot an s on sometimes.
Here's a little bit of a preview of what I've been working on lately. This is my team's current skin for the XFG. Still not fully completed, still a little bit of re-aligning to do, some text changes, roof/rear needs some flash on it. I also put in some custom dds files that I made. I edited the grill, and headlights. Mostly just tinted, but the headlights have some decals on it to follow the stripes, I think it gives it a bit more of aggressive look. Anyways, enjoy and feel free to comment, I like feedback.

What if he started poll, and you started last? Doesn't mean hes faster than you, he just had a better position. And thats what happens most of the time in karting, as the starting position for the first heat is randomly selected.
Like I said earlier, it’s being used all the time in karting; I've seen it being used at the local track stock car track and the local road course with the BMW series. Just because it's not on TV, doesn't mean it's not being used. As for NASCAR, I wouldn’t even really call that bump drafting, it’s more of a “If I let off the throttle, It’ll take another lap for my car to regain its speed. So I’ll just bump the person in front of me instead.”

Essentially what I'm trying to get at here is that bump drafting is very useful technique for cars that are very momentum driven, such as the XFG, as its underpowered engine can only pull the car along for so long. When you start racing the XFG, you are required to be on top of your game constantly, and being on top of that sometimes isn’t enough, as the driver in the lead is also on top of his. So when you’re racing against someone that’s close in skill level to yourself, you won’t be taking 1 second out of the 4 second lead that he has on you. You’ll be lucky if you get a quarter of that, and in sprint racing, there’s usually not enough laps to close that gap by just out driving someone. Drivers are forced to use another technique to close the gap between their car and the leaders. This technique is bump drafting. Although it can be risky if not done properly, bump drafting has a lot of benefits, but the main one is the extra boost in speed. This helps with closing the gap on the leader with out forcing the driver to be put under all the pressure of becoming the fastest car on the track. This also saves on tire wear and concentration, allowing the driver to maintain the amount of traction and focus he had before he started bump drafting, which will be crucial when it comes time to pass. I know all of this from experience. This is all stuff I had to over come as driver over the past 8 years of my career.
Hopefully that is understandable, my writing skills are not quite up to par due to my lack of sleep.
These two buttons should be used especially when you don't see the car that was behind you just before you started braking, saves a lot of accidents from ever happening.
Like TagForce said, there’s a ton of other motorsports where it is used. And using the 3 most popular ones where it isn't used, doesn't really prove anything besides the fact that bump drafting can't be used in anything open wheel, with weak/no bumpers, for the obvious reason. And if this is mostly what you watch/race, then surely you're going to think it’s stupid.
Yes, Wrecking is also another technique used to win races. But usually people don't get away with it. Thats why no one besides a few special little kids in demo use it, and they never seem to get away with it. I just don't see why people are affraid of taking a chance that can only benefit them if the process is done right. I mean you enter a race to get a chance at winning the race. The whole race is a chance, everytime you brake, it's a chance, everytime you take a corner, it's a chance, everytime you bump draft, guess what, it's a chance. And that's just another chance that's already on my "WILLING TO TAKE A CHANCE ON" list. 
Bump Drafting is one of the most useful techniques, plain and simple. Me and my cousin used it all the time in karting. We'd pull away from the pack, and then battle it out or we'd team up and work our way through all of the traffic. This technique has transferred over to LFS without a problem. We both understand when to brake, and when not to bump. Hell, we even bump draft in corners. Do I do it to people I don't know? Yes. Is it controlled? Yes. Has there ever been an accident because of it? Yes, mostly when people slam on their brakes. Maybe if people started to realize that when they are race there’s going to be contact. I'd rather it be controlled then "non-intentional". Thats my 2 cents, and my first post.
