I have actually never heard of the 3 second rule, just 2 as I was taught in the Netherlands. and believe me, driving rules in the Netherlands are rigourous.
In practice it depends where you drive. 3 second rule in the Netherlands might work. In Canada maybe, in Mexico definitely not (there they have the .1 seconds rule and a LOT of head tail collisions)
