I think it's only safer since we're doing less. We're more immobile; sitting on our phones, TVs, iPads. We order stuff online instead of going to the store. There's also less adventure without immediate reconciliation. We can corroborate if what we're doing out-and-about is correct from a simple google search anywhere, which reduces person-to-person interaction.
But there is zero evidence of this. Safety has been a long downward trend since the late 80s and early 90s in most places.
