As always, the downside to that is repair bills down the road. Not just from things wearing out, but apparently some of the sensors for those are integrated into the windshield.
It may cost more than you think to replace a windshield | Kelley Blue Book I generally generally catch a rock and replace a windshield every two years or so. Last winter I replaced one in each of my pickups, costing me 200$/per; this year I've already had the new windshield in my company truck repaired, and have a pretty good ding in my new Colorado.
