and if you want deer, come to the country, i have a doe eating grass in my front yard every night, and she's not afraid of my exhaust.

you are right tho. I've been living in my country, Indonesia, for years. We don't really sticking close to big trucks. It is scary to see those stuff falling off of the trucks and going straight through your windshield. My mom's friend was driving behind a truck, and yeah she was damn lucky. The pole just penetrated straight to the windshield and the passenger's seat.

I should say, "drafting behind a truck with container can be safe." I would not recommend anyone driving any trucks especially with stuff which seems not securely tightened.

you don't need to be inches behind the truck to draft it, two car length back will still net you an increase in MPGs.

Two car lengths back is nowhere near far enough. That's only a third of a second back at 65mph, which is nowhere near enough time to react if something were to happen (for example, a blowout or loss of tread on one of the truck's tires).

Your best reaction is almost always to brake. Swerving risks loss of control, and might put you in a worse situation, but braking hard in a straight line is a fairly safe bet. If you can't avoid hitting the animal, it sucks, but you're best off hitting the animal as slowly as possible.

Problem with that is your COG drops when you brake, raising the chance that the body enters through the windshield and DOES kill you. The better move is to accelerate and that's what any defensive driving course will teach you.

Mine is terrible... 10.5L/100km

Nope. The nose of the car drops slightly when braking, the CG remains at a nearly unchanged height, and at the end of the day, the biggest (by far) factor is that you hit going slower. Accelerating increases the risk, and increases the likely damage to your vehicle. If any defensive driving course teaches you to accelerate, I would seriously question the advice given in that course. All the actual advice I can find states exactly the opposite. For example:

You probably wouldn't want to panic brake, for the same reason that you wouldn't want to swerve: you want to minimize the chance of losing control and hitting something else. However, you do want to minimize your energy on impact as best you can, and this is ALWAYS achieved by hitting it at the lowest speed possible (assuming you can't avoid it entirely). Some sources also recommend releasing the brake just before impact, both due to the front end lift this will cause, and (again) to improve the chances you will maintain control throughout and after the impact, however this is very different than advising that you accelerate (which is pretty much never a good idea).

Forgive my terminology then, but if you brake and hood drops...the animal comes through the windshield. That was the main point, not some semantics argument. Your quote regarding letting off the brake addresses that concern to a degree, but I'm done with this conversation now.

I must agree with you. I don't think I'd be able to accelerate if that is a living thing. I just can't.

Heck i did a trip from seattle to spokane and back earlier this summer and did over 33mpg in my manual. I set the cruise control to 70 most of the way, didn't draft anybody and got bored on the way back and hit triple digits speeds so i could have gotten better than 33. If i had done 60 the entire way, and didn't have a mountain pass i'm positive that i could have bettered 33 by a few mpg. steady speed/throttle response and a flat road will net some really higher mpgs, add in some safe drafting and even more can be had.

another example is on my old speed 3, highway it's rated for 25mpg, my best tank was 35mpg on the stock tune, all highway doing 60-65 and yes i did draft trucks and stayed about 2 car length behind.

Oh I do believe that 33 is possible with all highway driving at the right speed. I just don't believe a person responded with 42MPG is valid at all. I wouldn't question it at all even if someone said 35, they're just driving all highways at the critical speed.

why you should stick behind a truck when driving on freeways at night.

Whoa, that was scary but avoidable. Depending on the driver if he was scanning the horizon he could see a group of deers on the left side. But of course not everyone does that. Even worse when they jump out from the woods or something onto the road. Luckily I live in CA cities and we don't have deers running around like that.

True but the user who said ~42MPG has a manual.
