In Ontario, Canada, the multi lane freeway limit is 100 km/h (62 mph)
On 2 lane secondary roads its 80 km/h (49)
Most people zip along up to 130 without much trouble.
The provincial police publically said that they will allow 120 km/h in good daytime weather and clear roads, but have a more severe attitude to poor driving, rather than pure speed.
As it should be.
