I would feel pretty safe running my own hand-written services against the raw Internet, but if I was to host Wordpress or other large/complicated/legacy codebases I'd start to get worried.
Also the CDN aspect is useful - having lived in Australia you like connections that don't have to traverse continents for every request.
On one hand, I'm okay with that. If Cloudflare or some other self-appointed Internet cop blocks me from a site, I just go somewhere else, and I hope the site goes out of business as a result...which happens to businesses everyday for a variety of reasons. But given Cloudflare's sheer size, having so many businesses crank the shields to maximum actually affects using the web, and that's where I draw the line.
Or roads are badly designed, in a way that their psychological speed limit is higher than what is indicated. But the lower limit can have more reasons, such as noise pollution near a residential area, or pedestrian safety.
I find that enforced speeding fines (which doesn't seem to happen in the US) causes drivers to drive at different speeds, whether an individual at that speed is safe or not. Inconsistent driving speeds is a lot more difficult to drive in.
If I had a vote (which I don't) I'd say increase all the limits by 10 mph (to reflect what people are doing now) but then also fine people that are speeding (like +2mph).
I'm going to need your home country for comparison - I find what you're saying here sounds a lot more like California (where I live now) than Australia.
I learned how to drive in Stockholm, which isn't great either, but doesn't get close to Australia.
By all means I think Vancouver and California drivers suck too :P I used to work in Vancouver CBD and witnessed several accidents people get hit by cars on the corner Robson Hornby. The city never did anything about it, it was just accepted as a fact of daily life.
EDIT a quick Google reveals people, including infants, are still getting hit and killed on the corner Robson Hornby, and it doesn't look like there's been any traffic calming or bollards or fencing or anything added to keep pedestrians safe. (people aren't just getting hit when crossing the intersection, they're getting hit by cars coming up on the sidewalks etc, it's crazy)
I've been living in the US for 4 years now (from Australia) and I find driving in the US, with their inconsistent-to-nonexistent speeding fines have caused driving to be a real pain - everyone drives at different speeds, mostly 10+ mph over.
Went to Australia last month - driving was so nice (yes, also to the Gold Coast). Everyone does the same speed (more or less); you can see cars in your mirrors and know they're going to be roughly in the same spot a second or two later when changing lanes :) :)
