Your better websites use "HSTS Preloading" to ensure users always get sent to the https version of the site - in which case even if the attacker redirected the DNS resolution, you'd just get an SSL error as the attacker wouldn't have a valid certificate.

Of course, an astonishing number of (even important, high-profile) websites don't bother with HSTS preloading ¯\_(ツ)_/¯
