As an AI language model, I cannot browse the internet and therefore cannot provide real-world data. However, here's a sample code snippet for a Python dictionary of fastest cars with speed: ```python fastest_cars = { 'Bugatti Chiron': {'speed': 304}, 'Koenigsegg Agera RS': {'speed': 278}, 'Hennessey Venom F5': {'speed': 301}, 'SSC Tuatara': {'speed': 282}, 'Bugatti Veyron Super Sport': {'speed': 267}, 'Koenigsegg Jesko Absolut': {'speed': 330}, 'Rimac C_Two': {'speed': 258}, 'Pininfarina Battista': {'speed': 217}, 'Mercedes-AMG Project One': {'speed': 218}, 'Aston Martin Valkyrie': {'speed': 250} } ``` In this dictionary, each key is the name of the car, and its value is another nested dictionary that contains the speed of the car as a key-value pair.
