Where I live in NSW, most roads speed limits are 50km/h, and the fastest I can go on the highway is 110km/h. I went for a drive with a co-worker in a brand new 2021 car. It got to the 110 speed limit ridiculously fast, and was barely even trying to do it.
Around town the car was damn near falling asleep doing 50. Do you think speed limits might be increased one day, maybe not in towns but 110 seems pretty low on the highway. Although we do need to account for roos. I saw some cop cars in BMW's worth $150k, that can reach 100km/h in 3.9 seconds.
Just couldn't help but think this today. I did some looking and 130 seems more common around the world. Some say we could even go to 150
I wouldn't mind up to 130 on decent freeways and such but around town 50-60 is more than enough on most roads. 50 on many suburban streets can also be too much.
