For anyone who didn't get it: You have to actually spell out what you want before you can say if it fits this answer or not. The car vs bike thing only makes sense if you didn't care how fast you got there, how tired you were when you arrived, or how much pain it was to haul the luggage there.
The answer to original question is easy in that light: Because IDEs aren't the only solution to the problem. Just because IDEs have a certain feature is no reason that other things can't have that feature as well.
(No, the correct answer to this is not "Don't carry luggage." You can't solve a problem by chopping its legs off so it fits in your problem-solving grid.)
For this particular example, you can apply this sequence of logic (with thanks to wccrawford):
if(Baggage) use a car.
else if(In a hurry?) use a car.
else if(Need to be rested?) use a car.
else if(Need to go 150 miles^ or more?) use a car.
else use a bike.
