> I assume if I run out into the middle of the motorway, I'm likely to get hit by a car. That's why I don't do that.

The problem with this is that governments are now requiring you to cross the motorway if you wish to continue having the friends you have already made, but promise that the motorways are now safe for you to cross and they will hold to account anyone who makes crossing motorways unsafe, and the DoT have said "Its fine, we have put in crossings on the motorway to allow you to do so safely!"

Your avg joe is going to take those reassurances made by multiple parties and assume the activity that would otherwise be risky is safe under these circumstances.

When people go on thrill rides at amusement parks and get injured because the operator or manufacturer fucked up, we don't blame the rider "saying they should know better, look at all of those ride failures in the news!", as they expected the ride to be built to a high standard, it be maintained, operated corrected, and have safety watchdogs keeping an eye on everything.
