I helped with a student team at my current uni that was building a hydrogen race car. The Formula Student team was just down the hall. Our uni's team was primarily fetishizing optimizations - I heard that they got one aerospace engineering student to spend an entire year on just the curve of the spoiler. While I had nothing to do with the technical stuff, adding enormous batteries and super high pressurized hydrogen tanks on student engineering calculations doesn't really...instill confidence. They got a Dutch former Formula 1 driver to give it a spin, and while he supported the project he was also very adamant that nobody should ever drive it that isn't a safety-trained racecar driver. (It's also not a large go-kart - more like a Lotus Elise size.)It's obvious to anyone who watches closely that the more innovative you are, the more likely you are to encounter problems no one has ever faced before.
