In "normal" times, ride hail drivers try to line up back-to-back rides. This is not just more profitable to minimize downtime, but also because, practically speaking, city environments where ride hailing is the most popular often have scarce places to park, even for just a few minutes. So realistically, expecting a driver to immediately find a place to pull over and spend 15 min sanitizing everything, while foregoing any ride pings that may be coming in the interim, especially if business is way down right now, doesn't seem likely.
