Yeah, obviously you "can" merge, but in doing so you insert yourself into the middle of a 2 second gap creating 2 × less than 1 second gaps. Like I said, in this hypothetical everyone is a perfect driver that always follows the rules, so that's not an option.
For that matter, the driver behind should see that you are about to merge into a gap that's too small and slow down to leave a space that's at least 4 seconds big.
I'd also like to point out that your attitude to driving is terrible, the size in meters of anything on a highway is irrelevant, 2 seconds is not a lot of time to react and slow down a car at 100, and that just because you "can" do something doesn't mean you should.
