当时贝尔曼驾驶的哈斯赛车以307公里时速疾驰，被迫紧急避让前方缓慢行驶的阿尔派车手科拉平托。两车相对速度差高达50公里/小时，场面惊心动魄。这种危险状况早在赛季初就已被多位专家预警。由于电能释放与回收系统已成为现代F1的核心技术，贝尔曼当时正启用加速模式，而科拉平托处于能量回收状态，这才导致了惊人的速度差异。
of course this rabbit hole goes deeper, and we have a paper using this technique for string constraint solving that i’d love to derail this post into, but i’ll save that for another time. the main point is that symbolic derivatives are a more powerful and efficient generalization of Brzozowski’s original idea, and they form the core of the new RE# engine. fun fact: symbolic derivatives are also implemented in Z3 (the SMT solver) for its sequence theory - so in some sense we’re inching closer to having an SMT solver’s core machinery inside a regex engine.
