Not the vehicle kind unfortunately.
Every now and then recently I've been getting automated error reports of a stack overflow exception in Scraps. But no-one's actually reported a problem to me directly, everything seems to be working perfectly for me (and clearly most others), and the error report doesn't come with any additional information.
So just putting out a general plea, if your game crashes or does anything weird, please do let me know and send me your output_log as described on the website Contact page.
