Wow,
Sounds like a close escape, especially as you ended up under the SUV. I hope you are OK and get your bike sorted out.
Just goes to show one of the key lessons I learned - if in doubt about someone having seen you - use the horn - not a long blast as if you're really p*ssed off, but a quick toot to wake up the inattentive.
Having lived in the USA my opinion is that the roads are safe but the level of awareness/observation of the drivers is lower than here in the UK. Maybe it's something to do with the level of training required to pass the test (I took my test in Ohio and it was so easy it was a joke).
By the way, we're in miles and MPH in the UK, same as you. But our gallons, and also our pints (hic!) are 25% bigger. Just in case you thought UK SV's are amazingly good on gas mileage (or our beer is amazingly expensive).
And as for BMW making SUV's - it's terrible. What a sellout. Whatever next - Porsche SUV's?
Cheers Keith
