Overview of Hotline: Folding phones in cars, EVs in Mexico
This VergeCast “hotline” episode focuses on listener questions about the future of car tech, especially how smartphones and EVs fit into vehicles that are changing quickly. Andrew Hawkins and the hosts discuss whether foldable phones make sense as car interfaces, why built-in wireless chargers often fail with newer phones, why maps matter more than CarPlay for some drivers, how EV startups can build better cars using off-the-shelf parts, and why Mexico is becoming an important market for Chinese EVs.
Folding phones as car interfaces
A listener asked whether foldables like the Galaxy Z Fold could justify their existence by acting as a larger in-car display, especially in minimalist EVs like the Slate truck.
Main point
- The hosts agreed that there is a real use case for foldables in stripped-down vehicles with little or no infotainment.
- In a car like Slate’s, a phone mount plus a foldable could effectively become the dashboard screen:
- navigation
- music/podcasts
- drone or utility control
- general “bring your own screen” convenience
Why it matters
- Slate’s philosophy is to remove almost everything from the car and let users add what they need.
- That makes a larger phone or foldable more appealing than a standard slab phone.
Wireless charging vs. modern phone design
Another listener complained that a newer iPhone with a large camera bump no longer sits properly on a built-in wireless charging pad.
Main point
- Built-in wireless charging in cars often becomes outdated faster than the cars themselves.
- Camera bumps, larger phones, and shifting form factors can make charging pads ineffective or inefficient.
- The practical solution is often still the old-fashioned one: plug it in with USB-C.
Key takeaway
- The hosts framed this as a classic car-tech problem: vehicles last a long time, but phone designs change quickly.
Where should your phone go in the car?
The conversation expanded into a broader question: even when you plug your phone in, where is the best place to put it?
Main point
- Automakers are still experimenting with phone storage:
- cubbies
- trays
- angled charging pads
- cupholder-like slots
- No solution is perfect yet, especially because phones come in so many sizes and shapes.
Notable insight
- Tesla’s angled charging tray was described as one of the better solutions, though newer camera bumps reduce how well it works.
CarPlay is nice, but maps are the real killer app
One listener said they don’t care much about Apple CarPlay itself — what they really want is good navigation.
Main point
- The hosts agreed that maps are often the most important feature in modern cars.
- Automakers are increasingly integrating mapping software directly into their infotainment systems rather than relying only on phone projection.
Why automakers are doing this
- Native navigation can use vehicle data:
- battery state
- range estimates
- charging information
- fuel levels
- route efficiency
- This is especially useful for EVs on long trips.
Trend to watch
- GM uses Google built-in.
- Ford is integrating Apple Maps directly in future vehicles.
- The broader shift is toward native or deeply integrated map apps that still feel personalized like CarPlay or Android Auto.
Practical gripe
- One host agreed that trip-time estimates can be emotionally destructive during family road trips and should be easier to hide.
Why EV startups still try to vertically integrate
A listener asked why more car companies don’t just assemble good cars from off-the-shelf parts instead of trying to build everything in-house.
Fisker as the cautionary tale
- Fisker was cited as an example of a startup that tried to do too much and failed.
- The company’s Ocean SUV became a symbol of overreach, software problems, and market turbulence.
Main point
- The hosts explained that many automakers believe vertical integration gives them:
- more control
- more future profit
- less dependence on suppliers
- But it also raises costs and complexity up front.
What’s happening now
- Some newer low-speed EV and golf-cart-like startups are more pragmatic.
- Companies such as those working with Magna may rely heavily on contract manufacturing and outside suppliers.
- Still, fully “Frankenstein” assembly from shelf parts is harder to make work economically at scale.
Mexico as a window into the future of EVs
A listener argued that Mexico is a smart place to look for the next wave of EVs, especially Chinese models that may eventually reach the U.S.
Main point
- Mexico is seeing a growing number of Chinese EVs and rebadged models from global brands.
- Examples mentioned included:
- BYD’s growing presence
- Chevrolet-branded Chinese models
- the BYD Shark pickup launching in Mexico before China
Why Mexico matters
- The country is becoming a competitive EV market with lots of cross-border influence.
- Canada is also seeing more EV imports, which means North America is increasingly getting “sandwiched” by EV-heavy markets.
Broader implication
- The hosts suggested that Chinese EVs may eventually enter the U.S. in some form, though likely with restrictions and caveats.
- They also noted that some Chinese-built vehicles are already sold in the U.S. under familiar brands, which complicates the policy picture.
Standout takeaways
- Foldable phones may actually make sense in minimalist cars as a bigger, do-it-yourself infotainment solution.
- Wireless charging in cars is increasingly mismatched with modern phone designs.
- For many drivers, navigation quality matters more than CarPlay branding.
- Native car software can do a better job using vehicle-specific data for EV routing.
- EV startups still struggle with the tradeoff between vertical integration and reliance on suppliers.
- Mexico is emerging as a key market for Chinese EVs and may preview what comes next elsewhere.
Listener sentiment and tone
The episode was casual, playful, and highly practical:
- lots of car-tech complaint therapy
- some genuine optimism about new vehicle interfaces
- a recurring theme of “the car is where old tech and new tech collide”
Follow-up-worthy idea
If the show revisits this topic later, the most interesting next step would be a deeper look at:
- foldables as vehicle control surfaces
- the best phone-mount/charging setups across car models
- how Chinese EVs in Mexico compare with U.S. market offerings
