I saw em. Nice pix. Slow as hell w/26K connection however.
You got off nice... there's a blue X at Courtesy Nissan today that's totaled. More front damage than yours, but the rear is clean... it must have gotten into engine and frame issues cause it really didn't look like a lot of damage...
Airbags have limits on firing - like speed, or impact angle. You mustve been just past the limit when you hit. No quite head-on enough to force a fire.
Glad you walked out of it.
