the roads aren't that well-maintained.. considering how slippery
the PIE gets just around the Chantek Flyover because the road there
is totally worn out...
and that's why the barriers there are smashed to pieces... they
were replaced and repaired regularly and if you pass there, you'll
see the barriers are usually new (meaning just replaced) and/or
smashed to pieces...
Yes, but that's not very common and it could be a lot worse in
places where the camber is adverse, the roads are lined with trees
or there's a bit of mist on the tarmac. Too many visitors
drive over-zealously, can't adapt to the changing grip levels and
fly into the scenery.
