Just want to add... its not only in the speed... its also on driving responsibly like pup2 said... right now i'm in canada for an extended business meeting and I drive a car everyday... their speed limit here is less than ours... 60 kph max... I'm sure most of us would say that on the open road 60kph is soooo slow... that's how i usually feel, but when in rome do what the romans do... respect their law...
even with their max speed a little bit lower, they still do have accidents... so better safe than sorry... avoid speeding, drive responsibly and be alert...
