I drove the Tesla Cybertruck. These 7 design flaws surprised me.

The Cybertruck's windshield is massive and more horizontal than many other vehicles. In the Texas sun, this didn't mesh well with the truck's all-black interior.Driving in direct sunlight, any part of my arm or leg that was exposed and not getting direct ventilation was uncomfortable, and I knew cranking the air conditioning would drain battery life.Inconveniently, the controls for the AC vents are buried in a settings menu on the main screen. No simple, one-motion adjustment of an air vent here — this is the future!Charging also got hot. It was barely spring when I tested out the Cybertruck, and within three hours of charging in the direct sunlight, temperatures inside had climbed to more than 130 degrees.Luckily, Elon Musk has tried to counter this somewhat with remote AC and window controls, and dog mode.Like most cars, the upper part of the Cybertruck's windshield has extra tint to help with glare. But unlike most cars, the Cybertruck's sun visor leaves some windshield exposed when unfolded for use — and plenty of sun can still wreak havoc.Don't forget your sunglasses! They won't just be to look cool.I learned the hard way that charging infrastructure in this country is still a long way from perfect. All Tesla cars come with an adapter for some slow charger plugs, as was the case in my Turo rental.But newer fast chargers not run by Tesla usually feature a plug known as CCS, which was basically the industry standard before a big switch to Tesla's plugs last year by most automakers.To charge at one of those, you'll need a different adapter that Tesla sells for $250. However, it specifically does not work with the Cybertruck because of its protruding plastic fenders. Some other Tesla models require a service appointment to make it work.Of the more than 40,000 public fast-charging plugs in the US, more than 60% are Tesla, according to data from the Department of Energy. Tesla's plugs are the clear winner here, but not being able to use any others could certainly be a headache.What are nervous passengers supposed to grab while warning you of brake lights ahead?!For a truck designed to excite, there's a surprising lack of oh shit handles for surprised passengers to grip during a terrified yelp while accelerating from 0 to 100-and-god-knows-what in a matter of seconds.It's like a roller coaster, except there also isn't room to fully extend your hands in the air either.To be fair, the backseat still has requisite hooks for hanging garments. No handle there, either.You better hope the automatic suspension adjustment to entry height when parking is enough. These standard handles are about accessibility.Wheel covers are a ubiquitous part of nearly every single electric vehicle. They improve aerodynamics by reducing drag, which helps range. In some cases, they look cool too.But unlike in some other Tesla models, the Cybertruck's plastic wheel covers extend beyond the tire. Even the lightest scrape of a curb is noticeable.Aesthetics aside, when you combine the truck's massive footprint and less-than-nimble maneuvering with tight spaces, it's a disaster waiting to happen.Sure, the buyers of a $100,000 truck are probably going to have a garage. But what about the trendy restaurant downtown with only street parking? Are you going to trust the valet with this? This rental Cybertruck didn't have Autopilot or Full Self-Driving yet, despite having all the necessary hardware. Still, I'm not sure I would have trusted it based on one incident alone.Let's set the scene:I was cruising down a highway at more than 70 miles per hour when I approached a flashing yellow light that warned of an intersection ahead. The truck suddenly started beeping incessantly and braking, despite no actual change in the road ahead.To be fair, Tesla does say in its manual that traffic-light and stop-sign control is a beta feature that may also stop at green lights.I appreciate the robo-concern, but the hiccup shows how many of these so-called edge cases will need to be conquered before true self-driving software can exist at any meaningful scale.This frunk is not safe.I placed a carrot on the open frunk's frame to test the sensitivity of the lid as it closed. The door sliced cleanly through the carrot.I'm far from the first person to use a faux-finger carrot in the front-trunk's closing mechanism. It still was unsettling to see in person.Most other cars have automatic sensors to detect a rogue body part in the way of a closing trunk or frunk, but apparently not the Cybertruck. Watch out for those fingers!Hey, at least it has a button for opening from the inside in case you are stuck or kidnapped (as required by law).

The Cybertruck's massive windshield doesn't mesh well with the Texas sun.

I questioned whether anyone tested the sun visors.

Want to fast charge on a non-Tesla plug? Good luck.

The truck lacks door handles in the ceiling.

The wheel covers are easily damaged.

Here's a close-up of the damage from the lightest of brushes with a curb.

Traffic-aware cruise control was far from perfect.

Beware, children, of the death frunk.
