The chase started in Murrieta in Riverside County. Here is a map that has Murrieta on it (south and east).
His end point was in Pomona, which is at the nearly eastern end of Los Angeles County. Just about everything due East & North East of Pomona is San Bernardino County.
West of where he started in Murrieta (up and over the coastal mountains) is Orange County.

In that map you can see how you can draw a frame to include the south west end of San Bernardino County, western Riverside County, eastern edge of Orange County and the southeast end of Los Angeles County, all within a rectangle about 25 to 30 miles long and maybe 10 to 15 miles wide, and with multiple possible Interstate highways within or crossing it.
