As far as city driving goes, I drive in TO too and my car get's the same exact city mileage no matter how I drive it.
Sheer city driving it's 500 km per tank, whether that be accelerating at stop lights, driving aggressively, or being the most gentle driver ever. If it's some mixed highway driving it get's about 600 km per tank. On the highway it's amazing, @ 120 it get's about 750-800 km per tank fully loaded with 4 people + luggage.
Car is an 2001 Lexus ES 300.
Manual recommends my tires to be at 28 PSI with capacity up to 4 people and speeds not in excess of 160 km per hour. 32 psi for speeds in excess of 160 km/h and 4 + ppl + shit in the car.
I run my tires at 39-40 PSI because on the sidewall the rating is like 44 max or some shit. I find I get better fuel economy and the car feels more responsive with that PSI. Tires are Goodyear triple treads 16 inch yo!
Honestly I see a lot of people trying to hypermile but most don't know what the fuck they are doing. They are all going way too slow all the time. Plus I find that in Mississauga every fuckin dumb idiot on the road is going under the speed limit. I swear to God, take Erin Mills at 4 pm where the speed limit is 70 km/h (naturally a good driver always does 10 over at least) and yet everyone is doing 60 km/h. It annoys the fuck out of me and I wish I had a rocket launcher to blast these baffoons from the road. Then you have those stupid bastards that drive side by side on a 2 or even 3 lane road per direction. Literally driving side by side at 60 km/h in a 70 zone for several stop lights, you can't even pass them. If I had a snow plow truck I would run them off the road. Or even worse are those that drive on a 1 lane per direction road under the speed limit, and then they come to a stretch with a passing lane, and either: A: They don't go to the right to let you pass B: They move to the right but suddenly accelerate 40 km/h more and now you're seriously breaking the speed limit just to pass them.
So in conclusion, for next season I will have train horn kits mounted on my motorcycle and my car. Actually I think Ill go with a vessel horn for the car.
Edit: Oh yes and I just wanted to add that I have noticed that most people who drive are zombies.
