Toyota went before the House Energy and Commerce panel Wednesday to voice its concerns

Toyota Motor Corp. is worried that Wi-Fi could mess with auto safety systems, and believes it could be dangerous without proper testing. 

According to The Detroit News, Toyota went before the House Energy and Commerce panel Wednesday to voice its concerns. John Kenney, principal research manager at the Toyota Info Technology Center in California, told the panel that the Federal Communications Commission (FCC) shouldn't allow Wi-Fi to use part of the spectrum designated for automobile systems until tested for safety.

“We don’t want a mom driving a car down the road with kids in the back seat, and because she happens to be driving by a coffee shop that’s using Wi-Fi, her collision-avoidance system turns off,” said Kenney.

Kenney said it should "be proven that no harmful interference will impair the safety-of-life mission for which that spectrum is allocated," including kids using devices in the backseat of a car.

Automakers are currently working on vehicle-to-vehicle (V2V) communication, which allows cars to "talk" to each other and communicate warnings to the driver as well. For example, your car could let you know that another vehicle ahead is about to blow through a stop sign in an attempt to avoid a crash.
In fact, the National Highway Traffic Safety Administration (NHTSA) said V2V could one day help prevent up to 80 percent of traffic crashes.
Automakers and governments have spent about $130 million for V2V research and testing. Also, 10 major automakers and technology companies have been working with NHTSA’s Connected Vehicle Research Program since 2012 in a V2V pilot study in Ann Arbor, Michigan.
Toyota clearly wants to see the technology work and be implemented in the coming years, hence its most recent Wi-Fi concerns. 
But Rep. Lee Terry (R-Neb) responded to Toyota's concerns, saying, “there is room for both.”

Are you referring to IFF or Next Gen (aka ADS-B)? IFF is pinged by the air traffic control system and goes to ATCs, who use the information to direct traffic. ADS-B actually works pretty much the same way, it sends position data to ATC computers who then broadcasts the locations to other aircraft. ADS-B is believed to use ground radar to prevent spoofing.

So, I don't believe that your comparison is valid. I do think that Toyota believes that others are ahead of them on this technology and are looking for a way to slow others down while they try to catch up.

Today's ATC uses humans that look at computer screens that combine radar and transponder data, so comparison not really the same....but maybe he's thinking of TCAS which is not air traffic control, but is a safety net for collisions. Which even that has cannot eliminate all factors such as the Überlingen mid-air collision (controller gave opposite instructions to TCAS which contributed to both descending) and the 737/Legacy collision over Brazil because the Legacy's transponder either malfunctioned or was accidently turned off. So, in a widespread deployment for vehicles, I think it's safe to say that similar failures would occur despite best laid safety plans.

ADS-B and the re-broadcast are pretty much done at the radio level out in the field, independent of any ATC equipment, which is why it's called automatic.
