    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.

    I have a question on this. Let’s assume everyone is a perfect driver and must have at least a 2 second following distance at all times. If there’s a free flowing queue of traffic on the highway with 2-4 second gaps between, merging in is impossible without someone slowing down and letting you in. Every time I merge this situation stresses me out.











  • By the way, 1 tablespoon of peanut butter does not weigh 14.79 grams. 1 US tablespoon is a unit of volume that’s equal to 14.79 milliliters(mils). Grams are a unit of mass. In order to convert between them we need the density. Because the metric system is great, the density of water is 1g/mil, so 1 US tablespoon of water weighs exactly 14.79 mils. However the density of peanut butter is a bit higher, so the US tablespoon of peanut butter will weigh a bit more.

    Additional pedantry, yes I did have to write US tablespoon every time. A US tablespoon is 14.79mils, a metric tablespoon is 15mils, a traditional Australian tablespoon was 20mils although now they mostly use metric tablespoons.
