How good are American roads?

Road dust, metals, and weird “urban mining”

• Some mention road dust being unusually rich in platinum-group metals from catalytic converters and brake/tire wear.
• Small-scale experiments and anecdotes (e.g., shop-vacuuming freeway shoulders) suggest you can recover metal, but it appears uneconomic at normal scales.
• Parallels drawn to sewer “gold panning” in jewelry districts: technically real, but marginal returns.

Car-centricity and what “4.3M miles of road” means

• Large US network size is seen by some as evidence of entrenched car dependence, induced demand, and associated health/emissions costs.
• Others argue raw miles are misleading: the US is big, rich, sparsely populated; road density and usage mix (personal vs freight, rail vs road) matter.
• Several commenters say the real critique should target urban/suburban design, not the mere existence of many rural roads.

How road quality is measured and felt

• The article’s focus on “roughness” (IRI) is welcomed but seen as incomplete; people care also about lane markings, reflectivity, signage, drainage, and junction design.
• Night-time/rain driving highlights huge differences in marking quality between states and even counties.
• Some note that potholes and sharp discontinuities feel worse than what a single averaged “roughness” number captures, though others point out IRI already simulates a “golden car” suspension response.

Climate, winter practices, and salting

• Thread challenges the simple “cold = bad roads” story: cold states like Minnesota and North Dakota can have good roads, while warm places (California, Texas) often don’t.
• Explanations offered:
  • Freeze–thaw cycles matter more than just low temperatures.
  • Salt is only effective in certain temperature ranges and can destroy both roads and vehicles.
  • Very cold or snowy regions sometimes salt less, plow more, or rely on sand/gravel.
• Canada and northern US see very different practices across provinces/states; some ban or minimize salt, others “brine the pavement”.

Regional and urban–rural disparities

• Strong perception of state-to-state contrasts: e.g., dramatic transitions at borders (Kansas–Colorado, Maryland–Pennsylvania, Arizona–California).
• Interstates are often praised while large-city streets (LA, SF, Dallas, Boston, Philly, Atlanta, etc.) are described as awful.
• Intra-metro gaps are big: affluent suburbs often have much better pavement and markings than poorer neighborhoods in the same region.
• Rural paved roads can be surprisingly good where traffic is light and there’s little underground utility work; truly unpaved or minimum-maintenance roads are a separate, often ignored category.

Governance, funding, and standards

• US patchwork (federal/state/county/city) leads to uneven standards and budgets; some places have sophisticated monitoring and tight maintenance cycles, others defer work for decades.
• Examples from Germany, UK, Italy and Scandinavia: similar multi-level governance, but more uniform technical standards; some EU-wide norms exist, though local variation remains.
• In US, choice of paint, reflectors, and lane design can vary widely by state DOT; some states appear to prioritize low cost over reflectivity or durability.

Underground utilities and road degradation

• Many argue that urban roads are rough less because of traffic volume and more because they are constantly cut open for gas, water, sewer, telecom, and then poorly patched.
• Repeated patching with mismatched materials, leaky manholes, and uncoordinated utility work accelerate potholes and settlement.
• Some cities try to coordinate: notifying utilities before big repaving projects or penalizing non-emergency cuts soon after resurfacing; effectiveness is mixed.
• Utility tunnels are proposed as an ideal solution in dense cores, but commenters note they’re extremely expensive and only plausible in limited areas or new-build cities.

Taxes, EVs, and how to pay for roads

• Several US states debate mileage-based road charges, partly to replace shrinking fuel-tax revenue from high-MPG and EV vehicles.
• Concerns: regressivity for poorer and fixed-income drivers; privacy and rent-seeking around GPS-based tracking schemes.
• Some prefer simple odometer-based systems; others push for weight×miles pricing to reflect actual wear, arguing that income-support should be handled separately from usage pricing.
• Registration surcharges on EVs and very efficient cars are cited as a common but climate-unfriendly stopgap.

Comparisons beyond the US

• Many personal reports say German and some other European highways feel vastly smoother and more consistent than US roads; lane discipline and intersection design also differ.
• Others note European city driving can feel stressful due to narrow streets and constrained parking but see that as a tradeoff for walkability and transit.
• Cross-border anecdotes (US–Canada, US–EU) often mention stark changes in smoothness, snow treatment, or maintenance style at national or provincial borders.

Meta: data vs perception

• Commenters appreciate the article’s data-driven approach but note that lived experience—noise, safety, legibility, driver behavior—often diverges from simple IRI scores.
• Some suggest weighting quality by vehicle miles traveled or population served rather than road-miles, which would likely make major metros look worse.
