lasers are pretty easy to deflect with reflective surfaces that can handle the energy input
It's actually a limitation of our brain. We can manage words up to reasonable length,
Your brain. Not our brain. Now get off my lawn, I've got the Rindfleischetikettierungsueberwachungsaufgabenuebertragungsgesetz to read.

In case you case, the two major shortcomings are power related (try to hotplug a wifi dongle, say) and the non-dedicated ethernet.
Suppose a car of m=1000kg mass.
Kinetic Energy E_kin = m/2 * v^2
E_kin(standing car): 0 J
E_kin(20mph ~= 9 m/s): 40.5 kJ
E_kin(80mph ~= 36 m/s): 648 kJ
E_kin(100mph ~= 45 m/s): ~1 MJ
Difference between the first two: 40.5 kJ
Difference between the latter two: ~352 kJ
I take the 20mph one, thanks..
