It can't give direction taps when dirving because you are stil bound by the junction you also need to be taking.
In the UK we have roundabouts so we always technically turn left in to our junction. our directions are "take the second exit", "take the third exit" etc. There is no way this is going to work on the watch.
The directional taps are only for walking, which you must dictate is what you want to do from the iphone or a verbal instruction from the watch "I want to walk to X".
Pretty obvious when you think about it, but must admit I tried it out this morning in the car before realising driving instructions were going to be very difficult to walking instructions.
Not had a chance to test out the walking instructions yet. Best test of that would be for a friend to punch in a mystery location on your phone and then for you to blindly navigate to it relying only on your wrist taps (whilst your friend has a bit of a head start and meets you there).

I tested it again driving home from work just now, and I definitely never get a continuous stream of 12 taps. Weird.
Yes.Do you get the 6 taps version for left turn instead?
What country are you based in Denzil? Do you wear the watch on your left or right hand?
The interesting thing is that if this works for some people and not others, it suggests it may be more likely to be a hardware problem than a software bug. Maybe the taptic engine on some models is unable to perform the 12 taps in a row.
In the UK. I really don't think the watch is at all safe or useful for in car navigation.
Maybe the user guide is incorrect?
I know John Gruber said recently he hadn't managed to figure out the 6 taps/12 taps thing himself, pre user guide - surely you'd be able to if it actually worked like that? 12 consecutive taps would be easy to distinguish from 3x2 taps.
While we're on the subject of taps for left and right - I'm a bit disappointed there's no distinct tap pattern for roundabouts (i.e. first exit, second exit etc) - would make navigating without looking at your watch much easier.
During my testing whilst walking, I've found that if you stop mid-route, then change the destination to be where you've come from, this will cause the app to become buggy - it will constantly tell you to do a u-turn, even after you've done so.Maps is a disaster for me. I can't distinguish the taps (except the arrival taps are different to the change direction taps). Maps doesn't seem to know where I am and keep trying to get me to go back to the start.
