It most likely won't be needed. It doesn't take much metal to set off the sensors and the engine, transmission, and suspension will be plenty.
You're probably right. Might work better on my smart since its engine and powertrain are all in the rear.

I've heard about using magnets to help trigger traffic lights. I'm not convinced myself that they really work. There's plenty of people that will swear both ways.

I suppose it's like those little ultrasonic whistle things people mount on their bumpers to scare deer away so they don't hit them. Some guy I know says people always asked him if they actually work. He said his usual reply is "I haven't hit a deer yet." But then it's been more than 20 years since I've hit a deer, and I don't use them, so...

Weight has nothing to do with triggering traffic lights. Most are loop detectors that use the metal in the vehicle, like a metal detector for prospecting for buried coins etc. Some use other ways like cameras, motion sensors etc.
Elio is bigger than a motorcycle so I don't think it would be a problem. I have a loop detector in my driveway to let me know if someone is on my property.
There is a "something" I had placed underneath my motorcycles that enhanced the recognition of the bike at such intersections

How to Trigger Green Traffic Lights
Questions and Answers

If you or someone you know owns a motorcycle, a scooter, a bicycle, or even a small car, you've probably noticed that it's easy to get stuck at traffic lights. An understanding of why it happens can reveal some methods that will help turn any red light to green. This will save time, gas and frustration by you not having you wait what seems like forever at a red light that has no ongoing

    [2][3] as to whether a magnet can alter the electromagnetic field in a way that triggers the sensor, since the sensors use signal frequencies in the many thousands of Hertz, not DC. You may decide to give it a shot. You can buy a commercial magnet or make your own.
    • If you do make your own magnet trigger, be very careful when handling them as they're very strong. Wear eye protection when handling them because they're very brittle, and if they slam together or against any other surface, a piece of magnet can easily get into your eye.[4] Protect the magnet before exposing it to the elements (e.g. put it in a chrome plated pill holder with a rubber ring). Never bring these magnets close to anyone with a pacemaker (the strong magnetic field can interfere with its operation), children (who can get their fingers pinched between two magnets, ingest one, or get a shard in their eye), floppy disks, credit cards, magnetic I.D. cards, cassette tapes, video tapes, televisions, VCRs, computer monitors, or any other electronic appliances.[4]
    • Attach the magnet case to the bottom of the vehicle with epoxy paste or screws. Where you place it on a car will depend on what kind of loop you tend to come across. If you want to cover all the bases, place magnets along the center and the sides (in line with the wheels). If you used epoxy paste, let it dry and check that the magnet is secure regularly--you don't want this magnet flying off of your car at 70 mph (110 km/h) on the highway.
    • If you ride a two-wheeled vehicle, you can attach the magnet to your shoe with epoxy paste so that when you pull up to an intersection, you're able to spot the wire and put your shoe right over it with the magnet.[5]

I'm not so sure........with all the aluminum used in today's small cars, even my smart has trouble some times (had trouble...I put some
Neodymium Magnets on the belly pan :)) . The "induction" loops will not see aluminum !
HOPEFULLY, there will be enough steel to trip them !!
