It means you've never traveled.
The driving time from LA to SF is about 6 - 6 1/2 hours if you don't stop. I'd rather relax on the train, use my computer, phone, or just enjoy the scenery.
I live in California and travel by Amtrak train. I use my lap top, read journel articles, and answer my email while traveling. Amtrak is economical and well set up to work. I enjoy the scenery from Bakersfield to Oakland. I have also had occasion to travel from Los Angeles to San Diego. The scenery was beautiful along the ocean.
That said, California cannot afford high speed rail. It would not prove to be popular either. Despite the governor's support, people are against it. Amtrak is highly subsidized as would a high speed rail.The best option would be to use the money to expand Amtrak lines, and provide connection service between cities. For example, Amway does not go over the grapevine into Los Angeles. A line could be opened through Tehachappi (only for freight at present) or one built over the grapevine for a more direct route. Subway connections could be expanded within the LA area to better connect Amtrak with various locales.
