Detroit isn’t the only city with outsized auto insurance rates

The Michigan Catastrophic Claims Association said Wednesday it would be moving to issue refunds to state drivers based on 2019 auto insurance reforms.

Crushing car insurance costs

Motorists in Detroit and much of the metro area -- as well as those in the Flint area -- are charged substantially more for car insurance because of where they live. All insurers, based on claims histories, opt to charge motorists more for most types of coverage. But in Detroit, costs for personal injury protection -- which in Michigan has no dollar cap, unlike all other states -- generates the biggest extra charges. Here is the map for AAA; other carriers show similar territorial rate differences.

For decades, Michigan residents have heard the complaints: Auto insurance rates are too high in Detroit, causing many motorists to lie about where they live, or drive without insurance altogether.

And for many beyond metro Detroit, they’ve probably thought: Not my problem; my insurance costs are fine.

But the high rates in Detroit are creeping into the suburbs and beyond, and with them huge disparities between bills in one city versus another. And numerous studies find Detroit and Michigan’s insurance costs are among the highest in the country.

A motorist in northeast Detroit may pay $2,128 for the same coverage that would cost someone a couple of miles away in Roseville $755 (motorists in parts of Grand Rapids would pay just $370). But higher rates now cover a substantial portion of Macomb County, from Warren to Shelby Township, and Oakland County. They’re also now found in Flint and much of Genesee County.

MORE COVERAGE: How Michigan’s auto insurance premiums became the nation’s highest 

It’s been allowed by state law for decades. After the Michigan Supreme Court ruled in 1978 that state regulators had failed to ensure that insurance costs were “fair and reasonable,” the legislative solution in 1979 allowed insurers to have up to 20 different “territories” where costs were different.

Auto insurance primer

  • Auto insurance premiums for motorists in Michigan vary wildly depending on a host of rating factors and discounts.
  • Car owners get discounts or additional charges based on their ZIP code, driving history, distance of daily commute, gender, age, education level, credit score and other non-driving factors.
  • When it comes to personal injury protection, which is legally required for all drivers, their ZIP code can be the most consequential factor in auto insurance in urban and densely populated suburban areas of Michigan.
  • Insurance companies use their claims data from prior years based on collision property damage and personal injuries to set rates for those portions of a driver's premium.
  • But there's no consistency in what rating factors insurance carriers use. For example, some use education level or job title, and others won’t.
  • Auto insurers are required to show the Michigan Department of Insurance and Financial Services only that the pricing behind the rating factors is actuarially justified.  

Back then, there were far tighter limits: Costs in two adjoining territories could not be more than 10 percent apart and the lowest cost in the entire state could not be less than 45 percent of the highest.

But that was too limiting for insurers and they successfully lobbied Lansing — first in 1986, then again in 1996 — for fewer restrictions. Insurers argued that it cost more for claims in areas like Detroit because aggressive litigation and higher per-claim medical costs put insurers at a disadvantage against companies writing policies outside of Detroit.

Now, insurers can charge vastly different rates depending solely on ZIP code or census tract — and they do. Some, including State Sen. Coleman A. Young II, now running against Mayor Mike Duggan to lead Detroit, called the territorial rates “the definition of redlining,” the illegal practice of withholding or changing credit or insurance rates based on an area’s race or ethnicity.  

Oakland County Executive L. Brooks Patterson, a frequent critic of Detroit, came to the city’s defense on this issue. He called territorial ratings that charge Detroit motorists’ more for insurance than his county’s drivers on the same vehicle is “classic redlining” and should be outlawed.

“The insurance companies have bitched about the costs, but they’re the ones running them up and trying to offset some of the cost in urban areas,” Patterson said in an interview. “They can’t have it both ways.”

Patterson, a longtime defender of Michigan’s unlimited medical benefits, said he favors getting rid of all non-driving factors in setting auto insurance rates.

“Oh, hell yes. That’s unfair,” Patterson said. “Then we do judge based on driving record and not how far you went in school and what’s your ZIP code. I don’t know how you can define redlining any better than what they’ve done in Detroit.”

Under current Michigan law, after all other factors are used — a driver’s record, age, gender, credit history, the value of their car –  insurers apply a geographic “factor.”

For example, let’s say that, after all other discounts and premiums are applied, the base cost for insurance for personal injury protection (PIP, the most expensive component of mandatory auto insurance) is $1,000  In much of Detroit, where the “factor” is 2 or higher, the cost for PIP would be $2,000 ($1,000 multiplied by the factor of 2) or higher. If the factor were 0.4, as it is in eastern Grand Rapids, it’d be $370 ($1,000 times 0.4).

Insurers have successfully argued that traffic patterns and congestion, varying medical costs and the differing likelihood of lawsuits in different neighborhoods and cities required different costs.

For the Michigan Health & Hospital Association, a trade group representing medical providers, the geographic rates for auto insurance are puzzling.

Chris Mitchell, senior vice president of the MHHA, which is monitoring reform efforts and resisting talk of setting fee rates for accident victims, said health care professionals don’t price their services based on where people live.

“In the hospital setting, when somebody comes in for an auto accident, we don’t ask them where they live and their pricing doesn’t change whether they’re from East Lansing or they’re from the city of Detroit, Livonia or wherever you live,” he said. “(Insurers are) the only people in this whole equation who ask where individuals live.”
