求翻译：昨天刚买完车，今天要回到旧金山，全程都是我自己开的车，下午4点从洛杉矶出发，我开了9个小时，第一次开这么长时间的车，开的我都要吐了。是什么意思？

Yesterday, just finished buying the car, to return to San Francisco today, the whole is my own car, 4 o'clock in the afternoon set off from Los Angeles, I lasted 9 hours, the first open car for so long, open I have to spit.
