Journey is usually safe. Just keep the habit of locking your
car. Cases of car robbery happens usually at traffic light and your
car is not locked. Or when you stop your car with your car being
unlock and unattended (E.g. Petrol station). So, keep a good habit,
but do not worry unduly. Just make sure car is locked whenever GF
is in car alone.
Directionwise, there is usually only two places where you might get
terribly confused. One is getting on the highway in JB. The other
is after exit near KL and turning onto Genting. If you already
farmiliar with JB, then that one should not be a problem. For the
one near KL, all I will advise here is that follow the sign to
Kuantan. If you follow that, you will get to Genting. Genting is
along the road from KL to Kuantan.
Carwise, you will have to go down to gear 1-2 in several places
near the top. So, be prepared for that. Personally, that is where I
find the most fun to play with gear. Feels cool to have the
constant need to switch gear all the time. In fact, I was like
playing daytona on the way up. On the way down, be warned! Don't go
too fast. the downslope makes the car accelarate easily and the
winding road is fun, but that is also where it is most
dangerous.
For a map, just go to another big bookstore either in Singapore or
JB. It is quite easy to find one actually.
