Fastest way from N. SD county to Las Vegas?

[KA24DESOneThree]

Yeah, so I'm heading to that Hankook drift event this Friday for some $30 instruction and track time. Trouble is, I'm going to be leaving Oceanside at around 11:15 and I have to be at the track by 4:30-5. I need to know the absolute fastest way from North SD county/South Orange/South Riverside to Las Vegas. No one-word answers like "110mph" or "airplane," please. I'm asking for the fastest way because I know I'll hit traffic. Btw, the way I'm going as of today is the I15 straight there.

I15 + Speed = fastest way.
Good luck getting there at 4:30-5.

extra quick note - if I15 is backed up by 15/215 split, take 215 all the way up back to 15.

I-15 should be the fastest way to vegas. its about 3.5 hrs from riverside so should be around 4.5 to 5 hrs from sandiego. If there are no delays in freeway then u should be right on time. But its Friday and I-15 is packed on friday. like mrmephistopheles said, u can also take the 215 all the way through san bernardino and catch the 15. its up to u. I was thinking of going also but my car got in a little accident and cant make it. Goodluck!!
