Oh wow, that happened yesterday how does that take out the train for 3 days?

Yea, it's very weird, makes me think that the trains aren't actually running or something

So far behind that they’re back on time

Here are some of the projects that could allow high speed Amtrak trains in San Diego (the article is missing electrification, which would help too). Many of these projects are already mostly planned, they just need funding. www.ridesd.org/posts/lossan...
San Diego High Speed Rail? — RideSD
High speed rail through the Central Valley is cool, but even cooler would be not-quite -high speed rail on the tracks connecting California’s two biggest cities—San Diego and Los Angeles. In the (hop...

All of the options piloted in that program had either:
1) major privacy implications by giving the government GPS tracks of everywhere the car went,

Or 2) could not distinguish between miles driven in jurisdiction and out of jurisdiction (a much bigger problem for a county level implementation)

None of those were designed to be reliable or tamper resistant enough to implement a major tax. Also SANDAG has no way of receiving the VMT from those systems.

And even if they did, SANDAG would also need to figure out how to retrofit every car that didn’t already have tracking.

SANDAG can’t even take credit card payments for bike lockers, 0% confidence they could develop novel tracking devices and deploy them at scale across millions of cars. (I doubt insurance companies would have enough incentive in making this work well for a single county either.)

I think there’s many practical engineering problems building something like that (making it reliable, tamper resistant, what if it break, etc). And the government sucks at tech.

I also think there’s practical political problems convincing people the devices only record distance and not location.

Government GPS trackers on every car seems so obviously outside the Overton window
January 15, 2025 at 1:15 AM
Yes, I personally do have some concern. But less concern for that than for a device I must maintain in my car that would give local government officials the ability to track my car anywhere in the world.
January 15, 2025 at 1:10 AM
I would not like a device in my car tracking me, and that option would have good-faith privacy arguments against it.

I think express lanes and freeway tolls make way more sense and most people already understand them.

Most of my mileage is driven outside of SANDAG jurisdiction, so why should I have to give SANDAG money for that mileage?

I’m in support of a road usage charge, but it never made any sense to me on a county/SANDAG level.

What were the good options for implementation? How could they have tracked only miles we drove in San Diego county?
January 14, 2025 at 4:49 PM
Blatant theft, that must be common given how complicated it was to figure out through the online Verizon billing portals
January 12, 2025 at 9:29 PM
Anyone know what time the new trains will be scheduled for?
