Probably a dumb question, but if you're driving along, slipstreaming
behind a van[1], does your presence have any effect on the van, e.g.
increased drag?

[1] Several feet away rather than inches.

Reduced, if any.

No idea about a bike but for cars it can actually decrease the drag on
the leading vehicle.

Does that mean that "tailgating"[1] is more fuel-efficient for both
vehicles?


[1] In quotes as what I mean is following at a certain distance, where
certain distance is less than the 2 second rule, for example.

In theory, yes. Close enough and the two bodies act as one much longer
one, which will generate less drag. One reason why speed record
vehicles are usually very long.

If you're close enough, yes.

A slight acceleration boost for the van when you ram into the back of
it.
