There are 130 road crossings on Brightline in the 112 miles between the Cocoa junction and the Loxahatchee River. 1.16 per mile. There are 39 road crossing in 47 miles between San Francisco and San Jose. 0.83 per mile. Fairly comparable, but Brightline has more per mile and they will run 110 mph there.
The 79 mph Miami to W. Palm Beach stretch has 171 crossings in 67 miles. 2.55 per mile.
Along the 110 mph stretch of Brightline are Cocoa, Palm Shores, Melbourne, Sebastian, Vero Beach, Fort Pierce, Stuart, and Hobe Sound. These are urban coastal suburbs of similar density to many of the suburbs between West Palm Beach and Fort Lauderdale. I know you already knew this, you live there on the central Florida space coast. Yet you continue to mischaracterize. That's a problem, not asking questions.
Those central coast urban suburbs are also similar to many of the suburbs along Caltrain that still have crossings.
Caltrain plus CAHSR plans for 20 trains per hour at peak. They estimated the gate down times would peak at 7 minutes 9 seconds in the worst hour for a representative crossing.

That may have been updated, but even if you double the gates down time, that is still less time blocked per hour than at a stoplight.
Many of the crossings are secondary roads with grade separations on many of the major roads. Total grade separation is not necessary to add CAHSR to the Caltrain line.
