Nevermind that 101 reasons, I can just name one ultimate reason : It can be quite irritating when you know that you know your way there and then this GPS shows you another way which practically took you cruising round the whole town before reaching your destination! Phew....
This is what happened when you become too dependant on that device. I wanted to go to TEN at Desa Sri Hartamas yesterday, and I wanted to see what was the fastest route there as it was already 7pm and the traffic jam could be quite bad, so I switched on my GPS. It's not that I didn't know my way, I just wanted to test out this device.
Mana tahu, this cute little voice navigator with moving map thingy took me through those back lane roads, housing areas and then roads with lots of traffic lights before reaching my destination. Without the GPS, I would just take the LDP and then go into Sprint and then exit at Desa Sri Hartamas. I went crusing the whole PJ from Sunway to SS3 to dunno where before arriving at my destination. One funny thing though - there doesn't seemed to be any traffic jam at the routes I took. Could it be because I selected the "shortest route" option or GPS actually shows traffic avoidance routes?!!
After this, I will only use the GPS for destinations that I have not been. If not, I will eventually loose my years of accquired sense of direction.
