I have a road bike and an e-bike (though I don't go "full spandex"). On the road bike, I both go faster on level ground and it's more of a pain to slow down, so I often will time passing more closely.

That being said, the most reckless riders I see are invariably teenagers on e-bikes (often illegally modified to go over 20MPH). Teenagers being reckless is nothing new I suppose.
