How well do cars do in crash tests they're not optimized for?
The whole car safety topic is very confusing. Car accidents is top1-top2 death reason in US for people in 20-40 age group [1]. Probably less in Europe but still one of the leading ones. I was thinking about how I can make myself safer.<p>Which car brand/model is better? 
Which seat is better for passenger?
How much riskier it is to drive during the night? In the rain? 
How dangerous is it to overtake on road with 1 lane in each direction?
What is most dangerous: crossroad with no traffic lights? Turns? City? Highways or smaller roads?<p>I was not able to find any meaningful research. There are ratings by different government agencies (US, UK, Australia etc), but basically all cars have highest rating which I find hard to believe.
