I would agree with wondering about the safety statistics. But I think the two main killers of GA pilots (1) running out of fuel and (2) continued flight into IMC (not instrument rated), are somewhat unrelated with respect to glass, so one doesn't count but could enhanced awareness be driving these non IFR pilots into the soup?

I know my fuel totalizer is hooked up to my 430 and if I put in a destination that is beyond the current fuel total at current flow rate, it will let me know in short order. Now I can screw that up by not setting it up properly, so that is why I time the burn per tank rather than trust the gauge only.
