The only solution I can think of that measures actual impairment is something in the car that monitors eye movement and such to see how often mirrors and such are checked.
But surely such a large dataset would be needed for this, and have regional variations? At night you are most at risk from sleep but consequently check mirrors far less as any car will be visible through headlights. I remember doing the UK driving test and consciously moving your head every five seconds to check mirrors - hugely distracting and yet going for much longer than that without obviously glancing at a mirror gets a minor fault. As soon as the test is passed this behaviour is put to the side as it's not practical in everyday use.
This is one area where manufacturers are a bit ahead of the curve. If safety guidelines include lane departure warnings on all new cars and other similar technologies then eventually these driving errors will start to decrease (hopefully). Car structures are so safe now that the safety focus should be on the driver rather than adding more heavy bodywork.
I think driver retesting every 5-10 years is possibly the best way to go to try and keep driving standards high.
On the second note, if Tesla's claim that they can prove their disputes with the data logging on the roadster proves true, than Tesla's going to win
OK but what is the chain of custody on these logs? If Tesla produces them two years after the fact that can hardly be introduced as evidence.
Some are Catholics, and believe in intercessory prayer, where you can't pray directly to God, even though that contradicts the entire Bible. You are dependent wholly on the Church still. You get forgiveness through the Church (not God) and must confess sins to a priest.
Where do you get that idea? The primal Catholic prayer is Pater Noster, directed directly to God. Nothing stops you from praying directly to God if you so choose, or Jesus, or the Holy Spirit. Prayers of intercession are a personal choice.
In modern Protestantism the vast majority of prayers are directed only to Jesus, not the rest of the Trinity.
Those who can, do; those who can't, simulate.
