yah, see, that's where you gotta be in tune. If they tailgate,
just switch to the left lane.
If not, it's probably low speed traffic. Drive slow and you'd
probably be fine.
With regards to the highway code, there has been no significant
inclusion of *any new road manners which one would expect from a
developed country with an appropriate developed level of road
systems.
Whilst I'm not about to whip out the highway code here, the book
which I studied was effectively the same which my aunt studied
(15-20 years ago?) and the one others have studied around 1 year
ago. Road rules, and nothing but road rules. Sure they've updated
the ERP timings and Bus lane timings as well, but that's not what
the highway code is really about, is it?
Now, the one that i studied in australia, that's properly updated.
inclusion of road rules, evasive actions, what to do when tailgated
etc etc, and the road manners which love_supreme so supremely
advocates. sure, we'd pick these up as we go along, but wouldn't it
be kindda nice if we gave the new drivers a better start? but i
digress, because i suspect this is entirely irrelevant to the
suggestions which love_supreme was making.
case in point, it shows how nonchalent the authorities' attitude
towards the driver's education is; with a somewhat apparent flawed
logic (or at least the prevalent opinion amongst fellow drivers,
your'e free to disagree) of 'make our test harder = better
drivers'. I think it's the beauracratic attitude which love supreme
can't stand, which i think is perfectly understandable.
