RC cars. I was into local club racing in the 90s, dropped out of it when my kids were born, now I’m getting back into it.
The technology improvements in power, battery capacity, and radios have been frankly astonishing. Setups that would have cost $1000+ back in the 90s come as ready-to-run kits for $200 now, and perform better.
The differences between victim survey statistics and crime reporting statistics are not easy to explain. In the US, trends in victim reporting tend to lead law enforcement statistics by a year or two, which makes one wonder whether law enforcement is padding the numbers – either to make themselves look good (when crime is increasing according to victim reports and it would reflect badly on them if LE statistics followed suit), or to make themselves look necessary (when victim-reported crime is going down and LE statistics might make LE look redundant).
