Today’s graphic provides an overview of the top imports across the Americas. For brevity, we’ve excluded regions with an import value below $1 billion.
The Top Imports, by Country
Petroleum is the most popular import across the Americas region. In fact, it’s the top import in 15 of the 22 countries included on this list: Vehicles are the second most popular, ranking as the number one import in four of the 22 countries. Cars are particularly popular in Northern America— they’re the top import in both the U.S. and Canada. Lastly, ships place third, snagging the top spot in three of the 22 countries. Interestingly, two of these nations are in the Caribbean.
The Top 10 Regions, by Import Value
When looking at which nations import the most of their top product, the U.S. leads the pack. In 2018, the U.S. imported $176.8 billion worth of foreign vehicles—around $147 billion more than its northern neighbor, Canada: The U.S. relies heavily on Mexico for its foreign vehicles—it imported over 2 million light vehicles from south of the border in 2018. Manufacturing of vehicles and associated parts makes up nearly 18% of Mexico’s total exports. Yet, while the U.S. imports a lot of foreign cars, the country exports its fair share of vehicles as well, especially to Canada. In fact, the U.S. is Canada’s top source for imported vehicles. The high volume of trade between Mexico, the U.S. and Canada is fairly unsurprising, given the trade agreement between the three countries. Since the North American Free Trade Agreement (NAFTA) came into effect in 1994, Mexico in particular has seen a significant boost in trade activity. In 2018, imports accounted for 39% of Mexico’s GDP—a 21 percentage point rise from 1994. »To learn more about the top imports worldwide, read our full article Mapped: The World’s Biggest Importers in 2018 Source: BACI, UN Comtrade Details: BACI is an international trade database, providing information on bilateral trade flows for more than 5000 products and 200 countries. It pulls data directly from the United Nations Statistical Division (UN Comtrade) Notes: For more information on methodology, visit the CEPII website on Today’s connected cars come stocked with as many as 200 onboard sensors, tracking everything from engine temperature to seatbelt status. And all those sensors create reams of data, which will increase exponentially as the autonomous driving revolution gathers pace. With carmakers planning on uploading 50-70% of that data, this has serious implications for policymakers, manufacturers, and local network infrastructure. In this visualization from our sponsor Global X ETFs, we ask the question: will connected cars break the internet?
Data is a Plural Noun
Just how much data could it possibly be? There are lots of estimates out there, from as much as 450 TB per day for robotaxis, to as little as 0.383 TB per hour for a minimally connected car. This visualization adds up the outputs from sensors found in a typical connected car of the future, with at least some self-driving capabilities. The focus is on the kinds of sensors that an automated vehicle might use, because these are the data hogs. Sensors like the one that turns on your check-oil-light probably doesn’t produce that much data. But a 4K camera at 30 frames a second, on the other hand, produces 5.4 TB per hour. All together, you could have somewhere between 1.4 TB and 19 TB per hour. Given that U.S. drivers spend 17,600 minutes driving per year, a vehicle could produce between 380 and 5,100 TB every year. To put that upper range into perspective, the largest commercially available computer storage—the 100 TB SSD Exadrive from Nimbus—would be full in 5 hours. A standard Blu-ray disc (50 GB) would be full in under 2 seconds.
Lag is a Drag
The problem is twofold. In the first place, the internet is better at downloading than uploading. And this makes sense when you think about it. How often are you uploading a video, versus downloading or streaming one? Average global mobile download speeds were 30.78 MB/s in July 2022, against 8.55 MB/s for uploads. Fixed broadband is much higher of course, but no one is suggesting that you connect really, really long network cables to moving vehicles.
Ultimately, there isn’t enough bandwidth to go around. Consider the types of data traffic that a connected car could produce:
Vehicle-to-vehicle (V2V) Vehicle-to-grid (V2G) Vehicles-to-people (V2P) Vehicles-to-infrastructure (V2I) Vehicles-to-everything (V2E)
The network just won’t be able to handle it.
Moreover, lag needs to be relatively non-existent for roads to be safe. If a traffic camera detects that another car has run a red light and is about to t-bone you, that message needs to get to you right now, not in a few seconds.
Full to the Gunwales
The second problem is storage. Just where is all this data supposed to go? In 2021, total global data storage capacity was 8 zettabytes (ZB) and is set to double to 16 ZB by 2025.
One study predicted that connected cars could be producing up to 10 exabytes per month, a thousand-fold increase over current data volumes.
At that rate, 8 ZB will be full in 2.2 years, which seems like a long time until you consider that we still need a place to put the rest of our data too.
At the Bleeding Edge
Fortunately, not all of that data needs to be uploaded. As already noted, automakers are only interested in uploading some of that. Also, privacy legislation in some jurisdictions may not allow highly personal data, like a car’s exact location, to be shared with manufacturers.
Uploading could also move to off-peak hours to even out demand on network infrastructure. Plug in your EV at the end of the day to charge, and upload data in the evening, when network traffic is down. This would be good for maintenance logs, but less useful for the kind of real-time data discussed above.
For that, Edge Computing could hold the answer. The Automotive Edge Computing Consortium has a plan for a next generation network based on distributed computing on localized networks. Storage and computing resources stay closer to the data source—the connected car—to improve response times and reduce bandwidth loads.
Invest in the Future of Road Transport
By 2030, 95% of new vehicles sold will be connected vehicles, up from 50% today, and companies are racing to meet the challenge, creating investing opportunities.
