I've got one section in play on almost every ride that has several manhole covers, assorted bumps, and several small asphalt repairs, all in a 100m stretch. Plus overhanging branches make the bumps impossible to see due to broken light on the road all times of day in that lane. Thank goodness for sparse traffic over 50% of the time, so I can take the left lane for that section, which is quite smooth. Otherwise it's below 30mph and focus on increased weight on the partially feet forward pedals.
On smooth road 40 is great with a long wheelbase, suspension or not.

Yeah there's a funny mentality surrounding road bikes. Like you said, going down a hill or powered by someone fit and healthy a road bike can really move, and go faster than many ebikes. People dont seem to worry about approaching the speed of sound on these impossibly light bikes (I'm sure the tyres and frames are filled with helium ) yet feel unsafe doing 30mph on even a reasonably well built ebike.
40mph isn't that big a deal to me, but head towards 50 and it starts to get a bit hairy. I've never ridden a road motor bike at high speeds but I've had my dirt bike up to around 60mph on a dirt road and felt pretty unsafe, even though it's designed to do it. In my mind its not so much the type of frame you're sitting on or the tyres under it, more so that fact that you're belting along on what may as well be a magic broom stick and if you and it should happen to part ways, for what ever reason, you or who ever gets your organs is going to know all about it
I guess if you're going to go fast you have to do what you can to minimise the risk of mechanical failure and leave the rest up to chance. (change being random unfortunate circumstances, or largely idiots who are unknowingly trying to kill you! )
