I won't miss him in the next movie - it's not about one person. Movie franchises such as James Bond, Star Wars, etc. survived the change in acting rolls, with other actors taking existing roles and characters being shuffled off. For me, he was a highly-paid actor that stupidly put other people's lives in danger by driving at ridiculous speeds on the public highway. I don't mourn the loss of Darwin candidates. Better he and the driver are gone without taking some innocent bystander out, than they continued their selfish and egocentric pursuits and ended up killing or maiming someone. Would there be such an outpouring of grief if Walker had been unavailable due to spending 10 years in the slammer for vehicular homicide?
