In Hong Kong it should be really early in the morning for reset time. There is no way to send 2 tickets (car) within 22 hours unless you skipped a day. And you must send it within 1 minute prior to reset.
*edit...does resetting the XMB time work to send 2 in a day? Never tried that.
The same thing happened to me. I tried to send a car to someone and I couldn't. It says that I have reached my daily limit, but I didn't send anything today. I sent something yesterday before 7pm Eastern time (server reset).
