i3 was a fascinating car and remains one of the best used cars currently available, but it had 2 bets that BMW lost badly. 1) That batteries would remain really expensive. Lithium batteries have been falling in price for a long time and EV

Mercedes is taking legal liability for their L3 system. That's better than Tesla GM's supercruise allows safe hands free driving as a L2 system. That's better than Tesla Waymo is operating a true L4 system in multiple markets

When I was a teen in Calgary the transit agency was really good at dealing with issues like this during peak periods. They would pair or triple busses together and alternate stops. If someone requested the stop the drivers would radio to co

Extensive analysis of Tesla and NHTSA crash reporting (some by NHTSA themselves) shows that autopilot and fsd do not have significantly better safety outcomes than manual drivers or drivers aided by other non-tesla assistance systems. This

The legacy car makers have flirted with 48V components for decades but haven't been willing to do the hard work to realize all the benefits it brings. The germans in particular are stuck in limbo. For their PHEV and BEV cars they are s

My mother did the exact same thing. When I was a kid we hosted a 3 refugee sisters who were new to Canada. Despite a significant language barrier my mother tried to explain the dinnerware was unbreakable and they didn't need to worry a

Especially with a robot that can harvest and sort different crops. Monocultures are unsustainable, but currently there isn’t really any other economic choice to keep a farm running. Technology like this is going to open so many new possibil

To be in the realm of fair non-compete compensation needs to be total comp and not just base salary. In the US while not working you need to cover healthcare costs and many roles have a significant portion of comp from percentages of sales,

Snowflake also made it hard to have good practices, giving them further culpability. There was no setting for customers to force their entire tenant to enforce MFA. Customers had to depend on each person with access to do the right thing, s

The problem with that plan is social engineering attacks. CSRs are often careless and will accept 'a bunch of random letters and numbers' as the answer rather than validating each character. Better to randomly select a long dictio

The range killer is really drag, not weight. Weight contributes, but at high speed drag is such a large draw that nearly nothing else matters. The rolling resistance coefficent of a car tire is about 0.01 and the force grows linearly with m

Under JR's definitions 150% capacity means people have enough space to read a newspaper. It's 200%+ that is the image of Japanese people being pushed onto the train by the white gloved staff.

Montreal's new REM is running pretty short trains at 30 trains per hour and still has capacity for over 40,000 people per hour. 60 trains per hour with longer trains can do even more. Only a handful of places on earth have the density

Ferrari broke their model this cycle. Their high end customers have put up with this for decades since the hypercars always gain value. Most people let them gather dust for a while, then sell them for a tidy profit once the Ferrari quiet em

Some of that blame can be laid at the feet of north american two staircase fire code requirements. Rules that all units need 2 different staircases really dictate the sort of layout that is physically possible, nearly always resulting in a

To nit the nit, Canada is a bicameral legislative system, but the upper house (Senate) is appointed rather than elected and is generally deferential to the House of Commons (though not always). Senators tend to sit for a long time and take

Porsche has a similar solution for race tracks and remote press events. A 2.1 MWh trailer that can dispense power at 3.2 MW. I think they are doing some clever things with solar to keep it charged (basically constant trickle charge with wha

Where train networks are extensive, frequent, and reliable the ridership numbers are huge, orders of magnitude beyond what a road network of equal right of way could hope to support. I have no issue with people choosing a car. I have issues

I'm comparing roughly similar right of way width requirements. Super-wide roadways are awful for pedestrian safety and walkability since it means destinations worth going to are further apart. Using huge amounts of space for the transp

Compared to the progressive utopia that is sitting in traffic? Passenger vehicle lanes move 1500-2000 cars per hour. Even with extensive carpooling and possible future technology that allows cars to bunch more, 10-15k people per hour is lik

Brightline itself is basically a property play. They buy up land around the proposed stations and then the train service makes that land more valuable and it's either leased or sold off for profit. The train is really a loss leader or

2 km long trains are not long in the US anymore; in the west 3-4 km lengths are being seen more and more often. Turns out slower, longer trains filled with bulk commodities are better for business since they don't have tight delivery d

Brightline managed to deliver their Florida line pretty much on time and on budget. The only real challenging part of the route is going to be pass out of the inland empire where the I-15 grade is a really steep. The rest of the project is
