You Know That First Minute Back in the Car
The steering wheel you can barely hold. The seatbelt buckle you grab through your sleeve. The wait while the A/C fights a cabin that sat in direct sun all day. If your car parks outside — work, school pickup, your apartment lot — that's not a once-a-summer problem. It's a tax on every single stop.
You've probably owned a sunshade before. It worked — you just stopped using it, because it was annoying enough to leave in the trunk.
