The energy density of fuel is much much higher than electricity, which makes using fuel to transport energy to where it is needed is much easier, and it makes the effective range for gas much higher because in those cases where you need it you can always just take extra gas (even taking into account the relative engine efficiency, to the worst possible degree gas is more than 10x the miles per kg than current battery tech).
Add to that speed of refueling vs. recharging, the many areas where power is not available at all, let alone super chargers (absent specialized charging hardware charging an EV takes days), etc fuel still has real value.
There are vast swathes of the world where grid power is not available, so the only available power is via diesel generators, which are generally around 40% efficient. At that point using an EV is not only slower, but at that point the best case efficiency (watts/kg) is less than 34% vs a diesel car engine's 43% energy efficiency.
If you have the right environment you might be able to use solar to charge the car, but I think for that you need something like 6kW of solar panels per car you want to use each day, and an additional car worth of batteries to store power during the day because you're presumably using your car at during the day. That's not a trivially portable system, so still doesn't fix the "I am driving a long distance where there aren't super chargers".
