NHTSA: Economic costs of car crashes $277 billion
I've provided two links now. Where are yours?
People will run malware for pennies.
The programmers, sysadmins, and netadmins can only do so much. If you completely lock them down, the users can't do their jobs effectively and/or whine and complain and not buy your software or use your service.
People do pay more for bulletproof software and systems, but most people aren't buying airliners.
$160 million per mile, to prevent an average of 50-60 tornado deaths per year?
1) Build 1000 miles? Only $160 billion? Is that cost of labor alone? What about the cost of land?
2) Build just for cities? Which cities?
3) How does a city afford even 1 mile of wall?
We can drop nukes in tornadoes too for much less, not that I'm advocating that either.
Just last year, there were 32,850 vehicle fatalities in the good ol' USofA.
Driverless cars would've prevented 99% of the crashes. Let's concentrate on rolling those out first and soon.
